If the little 18 year old was badmouthing and resisting arrest, as many of them are to do nowadays, 13 hits to the kisser isn't excessive.
As someone else already pointed out, we don't get to see anything that may have provoked the cop's response, or may be provoking it while it's going on. So we've gotta be careful about jumping to conclusions.
Also, did you see the 18-yr-old's picture? If that was taken right after the arrest, he sure looks awfully good for just having been punched in the face 13 times by a big bad brutal cop.
I don't know... It looks real bad for the cop, I'm not denying that. He may be a real ****ole and needs to be fired and imprisoned... But, I do want to hear his side of the story, and we never get that from the liberal media.
