I think, after watching, it was a set-up against the cops. The guy getting tazed knew he was being recorded, and wanted his 15 minutes of fame on vimeo/youtube. He pushed the officers until they had to do something.

I think the officers showed alot of restraint when he was mouthing off, and grabbing the officer's shoulders. He was given quite a few opportunities to back down peacefully.
