Sorry....she left "then got the gun" and came back...as a Juror...guilty.
If she would have stayed in the garage and then he came after her and then shot...different story. Unless she was sole owner of the home in question.
I would have hunkered down...had a bead on the door leading from the house to the garage and taking the pig out.
20yrs too much?...oh yeah...especiallly based on the history..if the facts are correct...it is what it is.
