The Conservative Trans Woman Who Went Undercover With Antifa in Portland
Confessions of a black bloc mole

Well, like the thread title says, here's some from a decent article/interview.
Small excerpt:

Strategically what they're doing is, they're forcing a dilemma action. A dilemma action is when you put your opponent in a no-win situation. Your enemy has to react. If they don't react, they look weak; if they do react, they have to react in a certain way where it looks like it's an overreaction.

Interviewer: When the feds were in Portland, they were presented as overreacting, a presentation helped by innumerable people with PRESS written across their clothing flooding the internet with images that presented protesters wholly as victims of an authoritarian regime.

That's their [antifa's] objective. It's not a tactical thing. That's why all the "press" is there, the sympathetic press. They're trying to create propaganda. They know how the police are going to react, so they carefully calibrate what they do to try to provoke the police into reacting and then filming it. They want to try to push public opinion in favor of removing the police. The police aren't perfect, but what police force is, it's putting force under an objective third party, under government control. Antifa wants to separate the police from the populace.

This is basically guerilla warfare. They're trying to undermine legitimacy of the state. The police right now, I think some of them are catching up. There's a playbook for how police respond to riots and they're not actually doing it; it's not an actual riot. I mean, it is a riot, but at the same time, it's a specific type of riot that's trying to make the police respond in a certain way.
