Apropos of absolutely nothing, a few random pieces of advice that you may or may not wish to follow.

I would also suggest you travel to the protest on foot, or by public transportation. If that’s not possible, park a good distance away and walk in. If you’re ubering (or whatever), have them drop you at a business a few blocks away. Makes it harder to link you to the protest later.

Also get the number of a good lawyer and write it on the back of your hand in marker that won’t rub off. Pieces of paper can be taken from you. Your hand can’t.
