2 words - jail time
I don't care how good your reason is... If you kick a dude in the head when he's lying on the ground covering up, in front of both a cop and a reporter with a camera, you're going to jail dude. 2 years for assault, add on another for a TSTL (too stupid to live) violation.
If I was the dude on the ground getting kicked in the head, I'd also go for the big civil suit payoff. Why not?
