I want to believe that the smartest, most capable people are defending us all from legit threats.

But how can you trust someone with subpoena power, or access to surveillance, or the authority to yell commands, or hell — even carry a Glock 19M Gen 5 9mm — if they're this dense? Or dishonest?

This is actual sworn testimony from a current FBI agent — who is the lead investigator in an ongoing trial about... you guessed it... protesters.

Trump’s Version of “Domestic Terrorism” vs. the First Amendment The administration has given itself permission to prosecute people and organizations for their political views.

Trump backed off calling Renee Good & Alex Pretti domestic terrorists because people didn't like it. But as I wrote, the admin is still doubling down on the use of domestic terrorism investigations to scare Americans away from using their First Amendment rights. www.brennancenter.org/our-work/res...

A letter to the director of the CIA from Senator Ron Wyden saying he has sent a classified letter that expressed concerns.

This is how Sen. Ron Wyden clues the public into activity that he finds extremely alarming. He does a press release about a letter he sent to the director of the CIA that basically says, 'I want to make sure you saw the classified letter I sent early today.' www.wyden.senate.gov/imo/media/do...

I wrote section 230 to protect user speech, not a company's own speech. I've long said AI chatbot outputs are not protected by 230 and that it is not a close call. Given that the Trump administration is going to the mat to protect pedophiles, states should step in to hold Musk and X accountable.

The Feds Want to Make It Illegal to Even Possess an Anarchist Zine Daniel Sanchez is facing federal charges for what free speech advocates say is a clear attack on the First Amendment.

“Prosecutors think they’ve found a constitutional loophole — if you can’t punish reporting it, punish transporting it.”

As a bookstore that sells pamphlets and magazines, the criminalization of such materials feels pretty close to home. So let's take a closer look at the materials the federal government is claiming tie readers to "antifa terrorism." We can pick out six titles in these grainy photos. 1/

Over a few months, a person driving around *one* town wracked up 526 location datapoints. We know that number because police were surveilling this person--but you can be assured the geolocation data you're leaving behind is similar and just sitting on a server somewhere. ALPRs are mass surveillance.
