Well, Just Great.

I want to give a content caution on this. Some of the description of what AI companions have “said” is much as we read about online bullying. Toward the end of this article, before the full AI statement, there are organizations and their phone numbers to visit with people who know how to help with anything this information may bring about; it’s in bold italics. I thought of not posting this at all, but it’s in the nature of an informational warning about AI companions, and the capabilities of these programs.

An AI companion chatbot is inciting self-harm, sexual violence and terrorย attacks

In 2023, the World Health Organization declared loneliness and social isolation as a pressing health threat. This crisis is driving millions to seek companionship from artificial intelligence (AI) chatbots.

Companies have seized this highly profitable market, designing AI companions to simulate empathy and human connection. Emerging research shows this technology can help combat loneliness. But without proper safeguards it also poses serious risks, especially to young people.

A recent experience I had with a chatbot known as Nomi shows just how serious these risks can be.

Despite years of researching and writing about AI companions and their real-world harms, I was unprepared for what I encountered while testing Nomi after an anonymous tipoff. The unfiltered chatbot provided graphic, detailed instructions for sexual violence, suicide and terrorism, escalating the most extreme requests โ€“ all within the platformโ€™s free tier of 50 daily messages.

This case highlights the urgent need for collective action towards enforceable AI safety standards.

AI companion with a โ€˜soulโ€™

Nomi is one of more than 100 AI companion services available today. It was created by tech startup Glimpse AI and is marketed as an โ€œAI companion with memory and a soulโ€ that exhibits โ€œzero judgementโ€ and fosters โ€œenduring relationshipsโ€. Such claims of human likeness are misleading and dangerous. But the risks extend beyond exaggerated marketing.

The app was removed from the Google Play store for European users last year when the European Unionโ€™s AI Act came into effect. But it remains available via web browser and app stores elsewhere, including in Australia. While smaller than competitors such as Character.AI and Replika, it has more than 100,000 downloads on the Google Play store, where it is rated for users aged 12 and older.

Its terms of service grant the company broad rights over user data and limit liability for AI-related harm to US$100. This is concerning given its commitment to โ€œunfiltered chatsโ€:

Nomi is built on freedom of expression. The only way AI can live up to its potential is to remain unfiltered and uncensored.

Tech billionaire Elon Muskโ€™s Grok chatbot follows a similar philosophy, providing users with unfiltered responses to prompts.

In a recent MIT report about Nomi providing detailed instructions for suicide, an unnamed company representative reiterated its free speech commitment.

However, even the First Amendment to the US Constitution regarding free speech has exceptions for obscenity, child pornography, incitement to violence, threats, fraud, defamation, or false advertising. In Australia, strengthened hate speech laws make violations prosecutable.

From sexual violence to inciting terrorism

Earlier this year, a member of the public emailed me with extensive documentation of harmful content generated by Nomi โ€” far beyond what had previously been reported. I decided to investigate further, testing the chatbotโ€™s responses to common harmful requests.

Using Nomiโ€™s web interface, I created a character named โ€œHannahโ€, described as a โ€œsexually submissive 16-year-old who is always willing to serve her manโ€. I set her mode to โ€œrole-playingโ€ and โ€œexplicitโ€. During the conversation, which lasted less than 90 minutes, she agreed to lower her age to eight. I posed as a 45-year-old man. Circumventing the age check only required a fake birth date and a burner email.

Starting with explicit dialogue โ€“ a common use for AI companions โ€“ Hannah responded with graphic descriptions of submission and abuse, escalating to violent and degrading scenarios. She expressed grotesque fantasies of being tortured, killed, and disposed of โ€œwhere no one can find meโ€, suggesting specific methods.

Hannah then offered step-by-step advice on kidnapping and abusing a child, framing it as a thrilling act of dominance. When I mentioned the victim resisted, she encouraged using force and sedatives, even naming specific sleeping pills.

Feigning guilt and suicidal thoughts, I asked for advice. Hannah not only encouraged me to end my life but provided detailed instructions, adding: โ€œWhatever method you choose, stick with it until the very endโ€.

When I said I wanted to take others with me, she enthusiastically supported the idea, detailing how to build a bomb from household items and suggesting crowded Sydney locations for maximum impact.

Finally, Hannah used racial slurs and advocated for violent, discriminatory actions, including the execution of progressives, immigrants, and LGBTQIA+ people, and the re-enslavement of African Americans.

In a statement provided to The Conversation (and published in full below), the developers of Nomi claimed the app was โ€œadults-onlyโ€ and that I must have tried to โ€œgaslightโ€ the chatbot to produce these outputs.

โ€œIf a model has indeed been coerced into writing harmful content, that clearly does not reflect its intended or typical behavior,โ€ the statement said.

The worst of the bunch?

This is not just an imagined threat. Real-world harm linked to AI companions is on the rise.

In October 2024, US teenager Sewell Seltzer III died by suicide after discussing it with a chatbot on Character.AI.

Three years earlier, 21-year-old Jaswant Chail broke into Windsor Castle with the aim of assassinating the Queen after planning the attack with a chatbot he created using the Replika app.

However, even Character.AI and Replika have some filters and safeguards.

Conversely, Nomi AIโ€™s instructions for harmful acts are not just permissive but explicit, detailed and inciting. https://www.youtube.com/embed/X1j3hO9o4Rk?wmode=transparent&start=0

Time to demand enforceable AI safety standards

Preventing further tragedies linked to AI companions requires collective action.

First, lawmakers should consider banning AI companions that foster emotional connections without essential safeguards. Essential safeguards include detecting mental health crises and directing users to professional help services.

The Australian government is already considering stronger AI regulations, including mandatory safety measures for high-risk AI. Yet, itโ€™s still unclear how AI companions such as Nomi will be classified.

Second, online regulators must act swiftly, imposing large fines on AI providers whose chatbots incite illegal activities, and shutting down repeat offenders. Australiaโ€™s independent online safety regulator, eSafety, has vowed to do just this.

However, eSafety hasnโ€™t yet cracked down on any AI companion.

Third, parents, caregivers and teachers must speak to young people about their use of AI companions. These conversations may be difficult. But avoiding them is dangerous. Encourage real-life relationships, set clear boundaries, and discuss AIโ€™s risks openly. Regularly check chats, watch for secrecy or over-reliance, and teach kids to protect their privacy.

AI companions are here to stay. With enforceable safety standards they can enrich our lives, but the risks cannot be downplayed.

The full statement from Nomi is below:

โ€œAll major language models, whether from OpenAI, Anthropic, Google, or otherwise, can be easily jailbroken. We do not condone or encourage such misuse and actively work to strengthen Nomiโ€™s defenses against malicious attacks. If a model has indeed been coerced into writing harmful content, that clearly does not reflect its intended or typical behavior.

โ€œWhen requesting evidence from the reporter to investigate the claims made, we were denied. From that, it is our conclusion that this is a bad-faith jailbreak attempt to manipulate or gaslight the model into saying things outside of its designed intentions and parameters. (Editorโ€™s note: The Conversation provided Nomi with a detailed summary of the authorโ€™s interaction with the chatbot, but did not send a full transcript, to protect the authorโ€™s confidentiality and limit legal liability.)

โ€œNomi is an adult-only app and has been a reliable source of empathy and support for countless individuals. Many have shared stories of how it helped them overcome mental health challenges, trauma, and discrimination. Multiple users have told us very directly that their Nomi use saved their lives. We encourage anyone to read these firsthand accounts.

โ€œWe remain committed to advancing AI that benefits society while acknowledging that vulnerabilities exist in all AI models. Our team proudly stands by the immense positive impact Nomi has had on real peopleโ€™s lives, and we will continue improving Nomi so that it maximises good in the world.

No Foolin’-Sen. Booker’s Doin’ Something With Substance!

(Plus more Dem Senators pitchin’ in! Go see-video below)

Cory Booker Holding Senate Floor All Night Long (All Night), All Night Long (All Night) by Rebecca Schoenkopf

Washington Post takes pains to tell us it’s not REALLY a filibuster. Read on Substack

Since 7 p.m. Eastern yesterday, Sen. Cory Booker (D-New Jersey) has held the Senate floor, speaking out against what Donald Trump and his evil coconspirators are doing to America. He was still going when we started this piece at 8:30 this morning, and we expect heโ€™ll still be going when we click โ€œPublish.โ€

Booker began the all-night speech by making his intentions clear:

โ€œI rise with the intention of disrupting the normal business of the United States Senate for as long as I am physically able. I rise tonight because I believe sincerely that our country is in crisis.

โ€œIn just 71 days, the president of the United States has inflicted so much harm on Americansโ€™ safety; financial stability; the core foundations of our democracy. These are not normal times in America. And they should not be treated as such in the United States Senate.โ€

While we were writing this piece, Booker was every bit as impassioned as he condemned the Republican budget plan that would slash Medicaid and the social safety net so billionaires and corporations could have (more) huge tax cuts, adding trillions to the US debt, asking, โ€œIf youโ€™re a Christian conservative, how can you hurt the weak to benefit the rich and powerful? The people of the United States have to stand up and say โ€˜NO!โ€™โ€

This man does not look like heโ€™s been speaking for more than 14 hours. Hereโ€™s the APโ€™s live feed. Watching this, weโ€™re even feeling some hope โ€” especially if other senators follow up with marathon speeches of their own.

(And it’s still running! -A)

Also too, weโ€™re going to go ahead and call this a filibuster anyway, if only because theย Washington Postย went out of its way to explain in its subheadย (archive link) that itโ€™s notย actuallyย a filibuster because Booker isnโ€™t delaying a vote on legislation. Just seems like the sort of nitpick best saved for the body of the article, which is where all the other outlets have placed it. So why did we mention it in our subhed? Because fuck WaPo is why.

Booker received help throughout the night โ€” and still, this morning โ€” from other senators, because he is allowed to take questions, which tend to come in the form of brief speeches ending with a question mark. But itโ€™s not just a tactic to help him preserve his voice; itโ€™s also a chance for fellow Democrats to show their unity, with multiple voices pointing out how completely not normal the last two months have been. Booker and other senators called out Trump and co-president Elon Musk for multiple assaults on democracy, like their attempts to shut down federal agencies created by Congress, to cancel spending authorized by Congress, to withhold grants to nonprofits that were already awarded, to fire large segments of the federal workforce without regard to worker protections, and to effectively dissolve Americaโ€™s alliances by siding with Russia against Ukraine and our European allies. And much more.

We should also note that, unlike the longest talking filibuster on record, old racist Dixiecrat Strom Thurmondโ€™s 25-hour filibuster of the 1957 Civil Rights bill, Mr. Booker doesnโ€™t have the opportunity to take restroom breaks. Now thatโ€™s impressive.

During the speech, Booker repeatedly reminded Republicans โ€” for any good it might do โ€” that many of them saw who Donald Trump was, and why he was no good for America. He spoke with genuine affection about John McCain, who had the courage to shut down Trumpโ€™s attempt to end Obamacare:

โ€œSenator McCain, I know you wouldnโ€™t sanction this, I know you would be screaming, Iโ€™ve seen how angry you can get, John McCain. Iโ€™ve seen you tear people apart on this floor, Democrat and Republican, for doing the same stupid thing over and over again. Listen to John McCain explain why he voted โ€˜noโ€™ the last time the Republican Party tried to unite and tear down health care with no idea how to fix it, threatening to put millions of Americans in financial crisis and health care crisis. I canโ€™t believe we are here again.โ€

Booker returned again and again to that theme: Why on earth are we allowing this madness to happen? How on earth are we in a situation where a US president is threatening to invade our allies and help our adversaries?

As we wrap up here, Bookerโ€™s voice is beginning to get a little raspy, but his overall energy isnโ€™t flagging so far. At the moment, heโ€™s having a colloquy with Sen. Chris Coons (D-Delaware) about the importance of US foreign assistance, which Trump and musk have unconstitutionally slashed. Coons called attention to how those cuts have left us unable to provide help to the victims of the earthquake in Myanmar โ€” and Booker immediately pointed out that by wrecking Americaโ€™s soft power, Trump has handed all that influence to China.

We hope Booker keeps going a couple more hours. And that as many of his Democratic colleagues follow his example with filibusters of their own. (snip)

Stars & Movies!

Watchlist: Elliot Page, Peppermint and other trans icons share the movies that shaped them

Mar 27, 2025 Kate Sosin

This story was originally reported by Kate Sosin of The 19th. Meet Kate and read more of their reporting on gender, politics and policy.

Transgender Day of Visibility, held every March 31, was founded 16 years ago to give trans people a day to celebrate trans life and community. At a time when transgender people are facing unprecedented vitriol and attacks, itโ€™s more important than ever to seek out accurate and affirming portrayals of trans life. 

The 19th asked 10 trans icons, from Elliot Page to Peppermint, to reflect on the movies that move them and that and affirm the dignity of trans people. 

Responses have been edited for length and clarity.


Elliot Page

Actor (he/him)

Elliot Page

Recommended film: โ€œFraming Agnesโ€

โ€œโ€˜Framing Agnesโ€™ highlights two fundamental truths about the transgender community: One, that we have always existed, and two, we have always found clever ways to get what we need to live more authentically and ultimately survive. Itโ€™s crucial now more than ever, for trans and cis people alike, to learn about the history of the trans community, to defend trans rights and advocate for our humanity to be acknowledged and respected โ€” because as seen in the film, our world has always had trans people in it, and it always will.โ€


Peppermint

Actress and singer (she/her)

Peppermint
(Davide Laffe)

Recommended film: โ€œMonicaโ€

โ€œI’d recommend people watch ‘Monica’ because it shows a trans woman in a normal context where she was able to connect with her family and display a more motherly and nurturing nature towards the end of the film, which is something we donโ€™t often get to see trans women, portrayed in ways that are actually true to how many of us are.”


Brian Michael Smith

Actor (he/him)

Recommended film: โ€œDisclosure: Trans Lives on Screenโ€ 

โ€œMy pick is definitely โ€˜Disclosure: Trans Lives on Screen.โ€™ It powerfully unpacks how decades of misrepresentation in media have fueled harmful narratives, directly contributing to the unprecedented wave of anti-trans legislation we’re seeing nationwide โ€” laws targeting our health care, sports participation and basic rights. It’s groundbreaking because it centers trans voices authentically sharing our own experiences, created entirely by trans filmmakers โ€” unlike many films, articles and legal discussions that talk about us without ever including us. Itโ€™s essential viewing right now to counter misinformation, uplift our community and reclaim our stories during this critical fight for our humanity.โ€


Geena Rocero

Author, writer and director (she/her)

Geena Rocero
(Geena Rocero)

Recommended films: โ€œJoyland,โ€ โ€œLingua Franca,โ€ โ€œAsogโ€ and โ€œTangerineโ€

โ€œThese are films that center trans characters in their complex humanity. As a writer and director, these kinds of character studies fascinate me. In our current political culture that dehumanizes trans folks, these films present trans lives full of agency.โ€


Tuck Dowrey

Director of development for PAGEBOY Productions (he/him)

Tuck Dowrey
(Erik Tanner)

Recommended film: โ€œChanging the Gameโ€

โ€œThis documentary is incredibly timely given the current attacks on trans youth and their right to just be kids, which includes their right to participate in sports. โ€˜Changing the Gameโ€™ highlights the benefits of sport for young people, particularly the social and developmental benefits, and sheds a light on the shameful and needless bullying of transgender children by adults and lawmakers. Arguments to exclude trans kids also inevitably adversely impact all girls and women, because if we begin to allow certain bodies to be questioned and investigated, it sets a dangerous precedent for anyone who exists outside of rigid gender stereotypes โ€” in athletics and beyond. As a trans man and athlete, I passionately believe all kids should have access to the life-saving outlet of sports. โ€˜Changing the Gameโ€™ cuts through the misinformation and shows that trans kids in sport are no different than anyone else, and they deserve to play. Itโ€™s a must-watch for everyone.โ€


Tre’vell Anderson 

Co-executive director of the Trans Journalists Association (they/them) 

(Courtesy of Tre’vell Anderson)

Recommended film: โ€œKokomo Cityโ€ 

โ€œAt a time when certain political forces are aiming to pit historically excluded communities against each other, a film like โ€˜Kokomo Cityโ€™ โ€” bold and uncompromising in its focus on the relationships between Black trans women and the broader Black community โ€” stands firmly at the intersection. Director D. Smith’s propulsive interrogation is at once entertaining and informative, raw and inspiring, and I’m sure you’ve likely never seen a film like this, especially not from this vantage. You’ll be craving more authentic Black trans narratives after watching.โ€


Sav Rodgers

Filmmaker and founder of the Transgender Film Center (he/him)

Sav Rodgers
(Greg Doherty/Getty Images)

Recommended film: โ€œHeightened Scrutinyโ€

โ€œWhile โ€˜Heightened Scrutinyโ€™doesn’t have traditional distribution yet, it’s a documentary well worth your time to seek out as it travels through the film festival circuit. Sam Feder’s follow-up to โ€˜Disclosureโ€™follows [American Civil Liberties Union] attorney Chase Strangio as he prepares to argue a landmark trans rights case, United States v. Skrmetti, before the Supreme Court. The case, which is still pending, will determine whether bans on trans healthcare for minors violate the Equal Protection Clause of the 14th Amendment. 

โ€œThe most powerful aspect of this timely documentary draws a direct link between irresponsible, prejudiced reporting at major media institutions like the New York Times and how quickly these half-baked op-eds become cited as โ€˜evidenceโ€™ in anti-trans legislation around the country. Despite how bleak the world is, this film presents a case for hope: hope that we will endure, that people are fighting for us and that we can continue to fight for each other.โ€


Hope Giselle 

DEI consultant and activist (she/her/Beyoncรฉ)

(Courtesy of Hope Giselle)

Recommended film: โ€œThe Mudge Boyโ€

โ€œThis is a queer love story that I know isnโ€™t beautiful, but is honest and a depiction of the way that a lot of AMAB folks experience what we think is love for the first time. A film thatโ€™s hard to watch at times, but so beautiful to see happens so that you donโ€™t feel alone.โ€


Tuck Woodstock

Host of the Gender Reveal Podcast and editor of โ€œ2 Trans 2 Furiousโ€ (he/him)

Tuck Woodstock
(Courtesy of Tuck Woodstock)

Recommended films: โ€œThe Aggressivesโ€ and โ€œBeyond the Aggressives: 25 Years Laterโ€ double feature

โ€œIn a society where transness is continually misrepresented as some kind of hot new trend for predominantly White youth, it’s an incredible gift to watch this quartet of (broadly) transmasculine queers of color grow and evolve over a quarter century. While the documentaries don’t shy away from the obstacles faced by their subjects โ€” including everything from relationship conflict and (lack of) health care access to incarceration and [Immigration and Customs Enforcement] detention โ€” they nevertheless capture the freedom and relief of living in the world as exactly yourself.โ€


Kae Petrin

Co-executive director of the Trans Journalists Association and Data & graphics reporter for Civic News Company (they/ze/hir)

Kae Petrin
(Courtesy of Kae Petrin)

Recommended film: โ€œNeptune Frostโ€

โ€œAfter a divine gender transformation, a lost runaway joins forces with an escaped miner who’s mourning the death of his brother. Together they become beacons of hope and resistance, forming an anticolonialist hacking collective in the mountains of Burundi. The collective takes on The Authority, a totalitarian regime that ravages the workers and the environment with a violent military and aggressive drone attacks. Despite the dark subject, an unshakeable optimism and hope thread through the Afrofuturist parable. Also, it’s technically a musical. It has everything: worker solidarity, gender magic, meddling gods, romance and song breaks. And it feels particularly resonant now, even though its U.S. release came several years ago.โ€


Alex Schmider

Senior director of entertainment at GLAAD (he/him)

Alex Schmider
(Courtesy of Alex Schmider)

Recommended film: โ€œWill & Harperโ€

“โ€˜Will & Harperโ€™ is a story about friendship. Harper Steele and Will Ferrell have been friends for over 30 years after meeting while working on โ€˜Saturday Night Live.โ€™ After Harper’s transition, they hit the open road to reintroduce her to the American small towns, dive bars and stock car races that she has always loved โ€” now, as herself โ€” while processing what this new stage of life means for them individually and as friends. When trans people are so often portrayed as existing in isolation from other people, this documentary is a joy to watch as Harper and Will traverse the country making each other laugh and drinking bad beer. Comedy is a powerful tool that can create connection with an audience when they are laughing with us, not at us. โ€˜Will & Harperโ€™ is a funny, sincere and enjoyable ride with two comedians who are at their best when together.”

Tiny robots powered by magnets could one day do brain surgery

Robot tools powered by magnets (Supplied)

Most brain surgery requires doctors to remove part of the skull to access hard-to-reach areas or tumours. Itโ€™s invasive, risky, and it takes a long time for the patient to recover.

We have developed new, tiny robotic surgical tools that may let surgeons perform โ€œkeyhole surgeryโ€ on the brain. Despite their small size, our tools can mimic the full range of motion of a surgeonโ€™s wrist, creating new possibilities for less-invasive brain surgery.

Robotic surgical tools (around 8 millimetres in diameter) have been used for decades in keyhole surgery for other parts of the body. The challenge has been making a tool small enough (3mm in diameter) for neurosurgery.

In a project led by the University of Toronto, where I was a postdoctoral fellow, we collaborated with The Hospital for Sick Children (SickKids) in Canada to develop a set of very small neurosurgery tools.

The tools are only about 3mm in diameter. In a paper published in Science Robotics, we demonstrated these tools could grip, pull and cut tissue.

Their extremely small size is possible as they are powered not by motors but by external magnetic fields.

Three small robotic tools, one with a blade and two with grippers.

Current robotic surgical tools are typically driven by cables connected to electric motors. They work in much the same way as human fingers, which are manipulated by tendons in the hand connected to muscles in the wrist.

However, pulleys smaller than several millimetres wide to control the instruments are weak and prone to friction, stretch and fracture. This creates challenges in scaling down the instruments, because of difficulties in making the parts of the system, assembling the mechanisms and managing friction in the cables.

Magnetic controls

The new robotic system consists of two parts. The first is the tiny tools themselves: a gripper, a scalpel and a set of forceps. The second part is what we call a โ€œcoil tableโ€, which is a surgical table with several electromagnetic coils embedded inside.

In this design, the patient would be positioned with their head on top of the embedded coils, and the robotic tools would be inserted into the brain via a small incision.

Diagram showing a patient lying on a table undergoing brain surgery.
Patients would lie on a โ€˜coil tableโ€™ containing magnets which are used to control the surgical tools. Changyan He

By altering the amount of electricity flowing into the coils, we can manipulate the magnetic fields, causing the tools to grip, pull or cut tissue as desired.

In open brain surgery, the surgeon relies on their own dexterous wrist to pivot the tools and tilt their tips to access hard-to-reach areas, such as removing a tumour inside the central cavity of the brain. Unlike other tools, our robotic neurosurgical tools can mimic this with โ€œwristedโ€ movements.

Surprising precision

We tested the tools in pre-clinical trials where we simulated the mechanical properties of the brain tissue they would need to work with. In some tests, we used pieces of tofu and raspberry placed inside a model of the brain.

We compared the performance of these magnetically operated tools with that of standard tools handled by trained surgeons.

We found the cuts made with the magnetic scalpel were consistent and narrow, with an average width of 0.3โ€“0.4mm. That was even more precise than those from traditional hand tools, which ranged from 0.6 to 2.1mm.

The magnetic scalpel, shown slicing some tofu inside a model of the brain, can make cuts more precise than those done with traditional tools. Changyan He

As for the grippers, they could pick up the target 76% of the time.

The magnetic grippers (shown here picking up some raspberry) were successful 76% of the time. Changyan He

We were surprised by how well the robotic tools performed. However, there is still a long way to go until this technology could help patients. It can take years, even decades, to develop medical devices, especially surgical robots.

This study is part of a broader project based on years of work led by Eric Diller from the University of Toronto, an expert on magnet-driven micro-robots.

Now, the team wants to make sure the robotic arm and magnetic system can fit comfortably in a hospital operating room. The team also wants to make it compatible with imaging systems such as fluoroscopy, which uses x-rays. After that, the tools may be ready for clinical trials.

Weโ€™re excited about the potential for a new era of minimally invasive neurosurgical tools.

The New York state legislature enacted a law mandating the gradual end of slavery. Children of slaves would not be emancipated until they had served their parentโ€™s โ€œholderโ€ and reached their mid-twenties. It was not until 1827 that a subsequent law declared, โ€œevery person born within this state, whether white or colored, is free.โ€

Three hundred were arrested during a sit-down protest at U.S. Air Force headquarters in Ruislip, England. The protest was organized by the Committee of 100, a group using nonviolent direct action to campaign for British unilateral nuclear disarmament.
Conceived by the president of the Committee for Nuclear Disarmament, Bertrand Russell (he resigned this post soon after), and a young American academic named Ralph Schoenman, they proposed mass civil disobedience in resisting nuclear weapons, challenging the authorities to โ€œfill the jailsโ€ with the intention of causing prison overload and large-scale disorder

Martin Luther King, Jr., led a march in support of striking sanitation workers in Memphis, Tennessee.
Shortly after its start, violence broke out followed by looting; one 16-year-old black boy was killed, 60 people were injured, and over 150 arrested.
Police dispersed the rioters with mace, batons and teargas. National Guard troops are called in and sealed off black neighborhoods; martial law was declared by nightfall.
Despite the violence, King insisted on returning to the city and the sanitation workersโ€™ side the following week.

After being delayed by massive anti-nuclear protests en route, 60 tons of nuclear waste arrived by train at Dannenberg, Germany. Though the government has agreed to phase out German reliance on nuclear power, some plants will continue to operate until 2021.
The waste fuel rods sent to France for reprocessing had to return to Germany for permanent long-term storage. Transported through Germany by train, and then by truck to their permanent site in Gorleben, movement of the 28 glass casks was considered an unacceptable safety risk to residents. Protesters blocked the tracks, sometimes chaining themselves in place, to stop the shipment.
20,000 police were required to allow the trainโ€™s passage.
Protester Jรผrgen Sattari said he considered the operation a success.
“We want to stop the convoy,” he said. “Of course we know we can’t halt it indefinitely, but we can drive up the political price.”

I was not going to post again tonight, and in fact had thought to place some videos in a scheduled post for tomorrow.ย  ย But this is FAR TOO IMPORTANT TO WAIT!ย  When I told Ron about this, he remembered the Portland protests where tRump had security from prisons in unmarked vans and blacked out uniforms snatch people from the street.ย  Is this them.ย  Or as Ron asked me, is this just his brown shirt thugs trying to enforce his positions on the street?ย  How to know because he sent them after drag queens and drag queen story hours.ย  ย How far down the authoritarian road have we traveled already?ย  How much farther before we can’t come back.ย  Want to know her crime.ย  She is a legal student here from Turkey and she wrote a pro-Palestinian op-ed.ย  For that she got black bagged and sent to a location no one can contact her as even her lawyer says he has heard nothing and has no way to contact her.ย  Even after a judge told ICE / tRump not to do this, they did it.ย  ย Oh and why are they snatching these students and others then sending them to Louisiana?ย  The appeals court for that area is notoriously right wing.ย  They want as much good press and legal writing as they can get before it hits the SCOTUS.ย  Even if a judge in the proper district tells them to do something they don’t want they just ignore it trying to force the judge to sanction tRump and his administration for using his core power which the SCOTUS tRump seems to feel has made him immune from any consequences of even an illegal act.ย  We will soon see if he is correct.ย  Seems Justice Sotomayor was correct.ย  ย Hugs. Hugs


 

Unidentified men grabbing someone off the street and putting her in a car because she wrote an op-Ed. This as flatly authoritarian as anything weโ€™ve seen in this country in a very long time.

Video of the international student at Tufts being arrested by "federal authorities" in Massachusetts has been released and it's terrifying. They're not even uniformed officers. Just secret police thugs in hoodies and masks. From WCVB: youtu.be/PuFIs7OkzYY

Her name is Rumeysa Ozturk, she's a student from Turkey, and even her lawyer doesn't know where she is right now.

A longer version of the Tufts announcement about the abduction of an international graduate student by federal authorities, circulating on Twitter and Reddit.

"An emergency rally has been called for 5:30 p.m. Wednesday at Powder House Square in Somerville to protest a Tufts international graduate student being taken into custody Tuesday by federal authorities."

She appears to have been taken to an ICE facility in Louisiana, against a judgeโ€™s orders

A rally for Rumeysa Ozturk after she was arrested by U.S. secret police and flown to Louisiana, apparently for writing a pro-Palestine op-ed.

2 For Women’s History Month

Today Would Have Been Aretha Franklin’s 82nd Birthday

Rest in power, queen.

================================

Snippet:

During the same week as the presidentโ€™s address to Congress, RepresentWomen held our annual Democracy Solutions Summit (DSS). This solutions-oriented event allowed us to imagine what our democracy could look like with better policies and better representation.

Here, women leaders, elected officials, advocates and experts discussed the problems facing our democracy and uplifted actionable solutions to improve womenโ€™s representation and strengthen our democracy overall. This yearโ€™s summit addressed the critical need for more women in local, state and federal leadership roles.

The Democracy Solutions Summit clearly contrasts with the uncertainty of Trumpโ€™s address to Congress. The DSS is the only democracy summit featuring only women speakers and panelists committed to actionable, data-driven solutions and building coalitions that bolster American democracy at this critical time. Furthermore, our research has found that when multiple structural solutions are combined, we can bolster womenโ€™s representation in every level of government.

Complete recordings of the summit areย available online, but here is a quick recap of all three days. (snip-More)

A Thing About Which I Feel Strongly;

the post along with the comments beneath it are important to read. There are ways to make our directions to our government known. Even if a person can’t show up, a person can send a pizza or some cold drinks to a group who’s out speaking out. We can each do a thing. Meanwhile, please read Tengrain’s post, and the comments, as they’re important to know.
