“People over Papers, a crowdsourcing project that maps sightings of US immigration agents, was taken offline yesterday by Padlet, the collaborative bulletin board platform on which it was built. It’s just the latest ICE-tracking initiative to be pulled by tech platforms in the past few days.”

the Trump admin just deported an award-winning journalist known for his reporting on ICE and got Apple to block ICE-spotter apps — all while churning out highly-produced social media content from violent ICE raids in Chicago. it’s their media or no media. www.techpolicy.press/amidst-viole...

Just amazing that, as things worsen week after week, the nation’s most powerful court keeps proceeding as though the gravest threat to our democracy is district courts failing to get out of the President’s way.

This is great news. CA law prohibits agencies from sharing ALPR-collected driver locations with out-of-state agencies. For years, @aclu-norcal.bsky.social and @eff.org have sounded the alarm bell about agencies violating it. In 2021, we brought the first suit to enforce it. More about the law:

Don’t believe anyone who tells you that intelligence shows anything “without a doubt,” but even if the intelligence was water-tight, this strike was still murder. No law permits the deliberate, premeditated killing of civilians.

“Distress detection” has the energy of “suspicious behavior reporting,” a bankrupt post Sept. 11th effort that needlessly put law-abiding people under government scrutiny.

BREAKING: Our client Mario Guevara, an Emmy-winning journalist detained by ICE in retaliation for livestreaming law enforcement activity, will be deported tomorrow to El Salvador.

Mario and his family are being punished for his reporting. This cruelty is meant to stifle our free press.

There is really never a good time to pass bad Internet laws that empower the government to control online speech.

But now is a really reallly really really bad time to do it.

Donald Trump basically announces that he is declaring war on anyone he deems a Democrat... and one of the leading Democratic Senators, @blumenthal.senate.gov thinks now is the best time for a bipartisan censorship bill that will let MAGA define what content is allowed on the internet.

WTF?
omarsbigsister.bsky.social
Are you kidding me right now? This is the last thing we need. KOSA is back no thanks to Senator Blumenthal who is working with the GOP and bringing in Republican Senators to convince the House to support it.

Please, CALL GOP House leadership and tell them to keep opposing it!

It really does not get more explicit than Trump telling top active-duty military generals that they will need to participate in occupations of large cities run by his political opponents as part of his "war from within"

Trump: "The ones that are run by radical left Democrats -- what they've done to San Francisco, Chicago, New York, Los Angeles. They're very unsafe places & we're gonna straighten them out one by one. This is gonna be a major part for some people in this room. That's a war too. It's war from within"

DHS subpoenaed Meta for information about an account that posts names and images of the ICE agents raiding our communities, but @aclu-norcal.bsky.social and advocates are pushing back.

Recording federal agents while on duty in public — and sharing that information — is our First Amendment right.

Mario Guevara has been detained by ICE for more than 100 days in retaliation for his reporting — even though a judge ordered his release on bond.

An immigration court just ruled Mario could be deported at any moment. ICE must free him now.

I'm just gonna keep reposting this inane BS from Justice Kavanaugh's concurrence on the roving immigration patrol case from LA.
The Government
sometimes makes brief investigative stops to check the
immigration status of those who gather in locations where
people are hired for day jobs; who work or appear to work
in jobs such as construction, landscaping, agriculture, or car
washes that often do not require paperwork and are
therefore attractive to illegal immigrants; and who do not
speak much if any English. If the officers learn that the
individual they stopped is a U. S. citizen or otherwise
lawfully in the United States, they promptly let the
individual go

Jimmy Kimmel was taken off the air after our government threatened a private company with retaliation, marking a dark moment for free speech in our nation.

More than 400 artists across our nation signed on to say: We refuse to be silenced by those in power.
We the people must never accept government threats to our freedom of speech. Efforts by leaders to pressure artists, journalists, and companies with retaliation for their speech strike at the heart of what it means to live in a free country.

Last week, Jimmy Kimmel was taken off the air after the government threatened a private company with retaliation, marking a dark moment for freedom of speech in our nation. In an attempt to silence its critics, our government has resorted to threatening the livelihoods of journalists, talk show hosts, artists, creatives, and entertainers across the board. This runs counter to the values our nation was built upon, and our Constitution guarantees.

We know this moment is bigger than us and our industry. Teachers, government employees, law firms, researchers, universities, students and so many more are also facing direct attacks on their freedom of expression.

Regardless of our political affiliation, or whether we engage in politics or not, we all love our country. We also share the belief that our voices should never be silenced by those in power – because if it happens to one of us, it happens to all of us.

This is the moment to defend free speech across our nation. We encourage all Americans to join us, along with the ACLU, in the fight to defend and preserve our constitutionally protected rights. A graphic listing the names of the more than 400 signers of the ACLU's letter condemning the federal government's retaliation against Jimmy Kimmel.
