legal jeopardy

Crime has increased and you have bought a gun. There is still the rule of law and home insurance will cover the losses from theft. A criminal has broken into your house while you are at home. Hopefully he intends to just steal. Will you engage the criminal to stop the theft at the risk of firing your gun or will you fall back with your gun to a defensible location and call the police? Considering the legal and psychological effects of shooting a person I have decided that my gun will be used only to protect my family not my property.
