Yep. First thing they taught us in BCT was that when you're off-duty and not in a combat zone, if a cop knocks you to the ground and puts his fat ass on your chest and/or throat in an attempt to asphyxiate you, you fight back.
He did the right thing, which was to give in, rather than be imprisoned. I wish it was legal to fight back...but we don't believe in repercussions for the unlawful actions of police. I mean, dude, they're the
police.
Unfortunately, due to our perverse legal system, he'll probably have a hard time even suing the cop, let alone having him prosecuted. 'What's that? You said a curse word? Oh, you provoked the cop. Clearly everything he did afterwards is moot.'
