I've worked in the prison system, this isn't an uncommon mentality. It's despicable for them to yell for "Help", play the victim & then carjack/rob them. The take-away lesson: "Have a plan to kill anyone you try to help". I work in EMS & try to take a constant role as a Good Samaritan, but at the end of the day, you should always have an escape plan & the means to defend yourself with a blade or bullets.
