Holy cow, what a story! That is nearly worst-case scenario with 2 guys getting the jump on you and a weapon pointed at you before you even realize it. It was his quick thinking that saved his life since his ruse gave him the few extra seconds needed to deploy his own weapon.
Thanks for posting this link. I plan to send it to every non-gun or anti-gun person I know because this is one of those "emotional" things that might change a mind or two. It also doesn't hurt that the victim is so soft spoken and comes off as a likable kind of person.
