The only way you should ever give chase is if the bad guy is running away with something thats worth taking a life over. Not things, but maybe a kidnapper. If the bad guy runs away then you are no longer in danger. Chasing them down and then shooting them can get you tried in court depending on how gun freindly the DA is. People can say or call me what they want, but I wont even leave my house to confront someone breaking into my car. Thats what the police are for. There are too many things that can go wrong and get you killed and I have kids to provide for. Now if I'm confronted in my home or out in public then I'm drawing my CCW and shooting. If they break off the confrontation then I don't have any business going after them.
