it was generally understood that a few of the people hanging around were cops. nobody pointed fingers at each other. and, the truth is that we weren't doing anything particularly sketchy, either.
but, i actually think the truth is quite a bit more startling than that.
i actually think i was at parties where 15 out of the 20 people in the room were cops. i think that it was cops that dominated the organizing committee. and, i ultimately think that the point of the whole thing was a sting.
so, it's not a question of finding the cop. most of the activists were/are cops.
