A friend of mine is a cop. He arrived at a domestic scene and the man in question was not wearing a shirt. My friend does not wear gloves and when he got in a wrestling match with the larger man could not get a grip as he was covered in perspiration. Wrestling with one hand while the other is trying to keep the gun from getting pulled away by the bad guy. 

One dislocated shoulder, concussion and sore ribs cost him 6 months off work.

He should have just shot the guy.
