"AS 11.81.350. Justification: Use of Force in Defense of Property and Premises-- (e) (2). . .a person outside of a vehicle may use deadly force upon another when and to the extent the person reasonably believes it is necessary to terminate what the person reasonably believes to be the theft of that vehicle when another person, other than the perceived offender, is inside of the vehicle; this paragraph does not apply to a person outside of a vehicle who is involved in a dispute with a person inside of the vehicle who is a household member of that person; in this paragraph, "household member" has the meaning given in AS 18.66.990 ."
     One has to read an entire statute to understand it:  ". . .when another person, other than the perceived offender, is inside of the vehicle."   That means a third party must be present, converting a property crime to a crime against a person.
     No endangered third party?  No shooting allowed.
     Simple.
