Holy fuck, I hope he's OK. He's not a socialist, but does fight for a multipolar world and has extensive knowledge of the inner workings of the US military apparatus.
Just in case anyone brings up his weird history of child sexual offenses, he was never prosecuted for harming actual children. Both prosecuted offenses were supposedly sting operations (aka entrapment) by FBI and police, which makes them super suspicious. For example, the first one in 2001 was conveniently timed to interfere with his anti-Iraq War advocacy.
The US government seized his passport in early June just to stop him from attending the St. Petersburg Economic Forum and derail his planned tour of Russia, where he would've gotten more coverage of his antiwar advocacy.
I would not be surprised if the FBI makes up a new sex offense charge based on this raid to try to shut him up about Russia, since that got the media so riled up the last 2 times. Another kind of bogus charge also wouldn't be a surprise.
