I still haven't seen the video - YouTube has a habit of cutting out on me midway through anything these days. I downloaded it last night, but didn't get a chance to watch before it was my bedtime.

That said, everything I've heard about the incident indicates that the police used disproportionate amounts of force, if they should have been interfering at all. It's incredibly disturbing.

Free speech limits are a bad idea, no matter where they're imposed (the classic "fire" scenario excepted, of course).
