I feel it is wrong and dangerous to carry fmj in a caliber that you know is going to go straight through the bad guy and kill the child other victim that is in the wrong place at the wrong time. Not to mention the legal problems that could come up. You are not responsible for the bullets that miss an attacker in the high stress moment. However if you make the decision to use a round that you know will cause collateral damage... That is just irresponsable!
