Basically: Leave your phone at home or faraday bag that shit, don't talk to press, don't post selfies on social media, don't be uniquely identifiable (visible tattoos, etc).

Same way all the idiots in Seattle/Portland/etc got arrested when throwing molotovs at police, looting stores, setting shit on fire and being dumb. Many are just one virtue signaling Instagram post away from incrimination.

If you're going to do illegal stuff, probably best to not let yourself be easily tracked regardless of political belief. Weird concept.
