Thats what zip-cuffs are for.
Anytime you strike a police officer then all bets are off.
One time, this little chick was in a crowd and randomly attacking people in the crowd. She was higher than Hillary after a ten minute speech.
I got called to the scene and the minute I walked up this chick walks up to me and bitch slaps me in my pretty face.
I coulda' knocked her the F out. That would be my normal instinct if I had assessed her as a threat. But there were tons of people around so I just bum rushed her into a secure area, took her down, cuffed her, and locked her up. Case closed. She did me no damage. The only thing she hurt was my pride.
We are trained to make instantaneous threat assessments and take necessary actions. This chick was no threat to the cop. She was pretty well restrained, though they left her hands free to their chagrine. Sucks to get bitch slapped, though.
This cop was out of line.
