A year ago my niece was held up at gun point in an attempted car jacking. Her boyfriend pulled his weapon and shots were exchanged with the boyfriend taking a bullet in his leg and the would be car jacker running away. The police were called. The boyfriend was immediatly arrested for trying to car jack my niece and my niece was arrested for a moldy old joint found in her boyfriend's car which she was not driving. The officers then proceeded to pat my niece down making lewd comments about her ample chest while "searching" her if you get my drift.
All this to tell you that had I been there two cops would each have a new hole in their heads for assaulting my family. The instant your safety, liberty, or person is jeopardized by a "government official" is the instant leathal force is justified.
