So, sort of piggy-backing on this, just read this today:

Basically, a black actress was talking and "being affectionate" with her husband. Apparently, some cops thought she may be a prostitute, came up and asked for ID. She refused, so they cuffed and detained her until her husband gave some ID, then released her (something like that anyway).

Someone asked a good question: Under what conditions can a cop ask for your ID, and under what conditions can you legally refuse? I do remember about, oh, a month ago or so, there was an infowars vid a guy took of two cops coming to his house, demanding ID, claiming someone'd said he was the perp in some crime nearby, and he refused to give up ID, and while there was a big hassle he "got away with it."
