He has a past history of violence, just slashed his girlfriend and is holding his dad hostage when he decides to go at the cops with a knife and shotgun. Yet now his parents and friends claim he was executed wrongly by the cops. Quit using the cops as your referee, councelor or whatever. You called them about your constantly out of control family member and they took care of the problem for you so stfu.
