"But if there aren't any actual threats towards the Good Samaritan and let's just say it's the store clerk who seems to be being threatened and is in harm's way then our Good Samaritan can certainly take matters into their own hands and do what we call a defense of others.”
Wrae says the customer had no obligation to run away from the threat. But there's no obligation to draw his gun and intervene either. She compares to a doctor who may decide not to stop and help at a car accident.
"They don't have to pull over. Usually, it's just their own conscience and goodwill that's making them stop and intervene and help out."
Police say they're still investigating this case. It'll probably be up to the Pima County Attorney to decide if the customer broke the law.
