Its called criminals are expected to be stupid, usually burgulars will run away when they see someone, so why shoot, oh yea, its called homeowner doesen't give a @#!% about the lives of others. Homeowners should be smart and maybe escort the person out of their home peacefully and shoot them if they resist or pull out a knife.
