Your not wrong. The castle doctrine states your vehicle is an extension of your home.Anyone remember this one?

Oklahoma's law states that a person who is attacked in their home "has the right to stand his or her ground and meet force with force, including deadly force, if he or she reasonably believes it is necessary to do so to prevent death or great bodily harm to himself or herself or another or to prevent the commission of a forcible felony."
Well we know this applies to your home.... but I believe this applies to your business and auto as well? Someone correct me if I'm wrong.
