Killer- As I said I can handle a thief without help. I do not rely on anyone other than the police to help me with anything security related. Police are trained to deal with criminals so I suppose I rely on them to handle that but that is the system we live in. There are other ways of dealing with people. In the world I live in a gun is a near last recourse of a reasonable train of thought and action. If it is the first thing you reach for then things have gone poorly or you are the one responsible for the outcome of every encounter. BTW- Tresspassing and burglary are quite different than shoplifting in that there is a presumption of violence as the actors motives are unknown. My comparison was beteen two non-violent crimes. Check fraud and shoplifting.
