What I know of protests in the United States comes from books and the media; I sure as hell don't involve myself in them when I'm down there, being a foreigner and all. I stumbled upon one while I was in Portland, though - a small one, assembled on the occasion of Mitt Romney being in town for some reason or another. What struck me were the number of police officers on the scene, practically one cop per demonstrator. I wouldn't be surprised if this is a normal sort of turnout.
