Ummm... Sarge, lemme tell you a little secret: You can harrass the E3s and E4s all you want, but DO NOT harrass the police!
This guy recently returned from Iraq. I little TLC might be in order, since I doubt very seriously that he is adjusted to civilian life or life in the US in such short order. Guys need a little time to make adjustments. During WWII, they came home on troop ships, they had the time. Everyone flies home now - no cool down time.
Quite frankly, I’m sure this guy was carrying a bit of an attitude, but probably didn’t call for a beating.
