If they have a gun they probably would have already drawn it.
I saw a video where two black men attempt to grab a bag off another man. He resists, he gets punched in the temple and falls over, and one of the muggers proceeds to draw a glock out of his jacket and unloads the entire clip into his head.

you don't know.Stop trying to pin certain solutions on a completely and utterly random scenario.
