My wife asked me a hypothetical question. We are in TX and here is the scenario... She had a flat tire and had to pull over in a secluded area. A stranger stops and offers help and she politely declines and requests the stranger to stay away (repeatedly). Stranger continues to approach and she is starting to get worried and scared. Short of running back inside the car...when can she draw and not be charged of brandishing or deadly conduct (if the stranger reports her after)? Should she call in a 911 report to the police shortly after? Any other things you can suggest in this scenario will be much appreciated.
