Btw, it appears he was possibly going for the mans gun when he was physically grabbed him from behind. It's never a good feeling if your armed and someone comes up behind you like that and grabs you. That's no bueno.
Was he taken into custody? He should have been. Reaching for a security official gun around here is the same as reaching for LEO. They are deputies of sheriff. What’s NY law ? Imagine it is the same.
