You can't see it in the video but apparently the big guy in orange had been handed a baseball bat later in the whole episode. I don't know for sure if that's true, because the video does not show him beyond a certain point.
I'm not blaming him, but I really wish he had just gone inside and called the cops. if so the gunmen would have been arrested for pulling guns on him and been headed to jail and he would still be alive. very unfortunate.
