Okay, here’s a textbook case (your State’s law may vary):
• “Castle doctrine” generally means that the law presumes that someone unlawfully entering or inside a home is a threat, so the resident does not have to show they feared felonious intent.
• The resident decides whether deadly force is necessary.
• The law does not require that the resident consider escaping (i.e. no “duty to retreat”).
• There is no requirement to issue a warning. (With witnesses around, however, it may be a good idea to do so.) “Warning shots” are generally illegal (besides, where do those slugs end up?).
• Shut. the. heck. up. Make a full and honest statement to police, but only after you have a lawyer to help you avoid saying something inadvertent that will be used against you. Before then, say only something like, “I defended myself. I’ll be glad to make a full statement in the presence of my attorney.”
• Do. not. talk. to. the. press, to the perp’s family, or even to your own family (they might then be called as witnesses). Do not brag, do not embellish, do not alter the scene, and do not greet the police armed (they won’t know who’s who).
• You’ll be under severe emotional and psychological stress. Keep only supportive people around, and avoid anyone second-guessing your action. Seek professional counseling, if necessary.
(What? No, I’m not a lawyer, but I teach this stuff in the occasional NC CCH class. Take it for what it’s worth.)
