well, i am in no way defending him; but look at it like this. Three really BAD guys break into your house in the middle of the night. They make threats that if you dont listen to them they will kill you and your family and that they will come find you where ever you hide if you tell the cops. You get the chance and blast on in the skull. the other 2 break for the door. Would you let the run, having to worry the rest of your life about them coming back or would you take them out??
