I dont think i would lose an ounce of sleep if i had to take someones life that threatend me or my family's life.I had a freind that ran a storage center,he came out of a back room to find 2 black guys with a gun to his wifes head,he pulled his gun and shot them both,one lived and one died,he says he would do it again in a heartbeat.If he did not pull his gun out and shoot,he said him and his wife would have problely been killed . These scum today just cant rob you and leave ,they feel the need to kill.
