Policeman is paid to subdue the hippy
Policeman's personal agenda is not to get stabbed with aids needle or otherwise molested.
Policeman bootcamp understand this and train in effective methods of subduing fuckheads.
IMO the policeman in this vid went by the numbers - that's how to safely diffuse an idiot.
Thats why I say the policeman thinks he's doing the right thing... it's not "normal" to deal with weirdo who isn't violent, you get a non-violent weirdo in front of you acting like all the violent ones and *bang* into subdue mode.
He was gesticulating wildly, shouting and then he threw his cigarette at the cop's feet. That was aggressive body language. Srsly - I've hospitalised people for less. Plus the cop was asked to be there by the restaurant who claimed he was hassling people.
