I remember what it's like to guess what a guy is hiding in his pocket or behind his back but, geez, context is everything. An argument over admission hardly gives rise to assumptions the dude's about to pull a Thompson submachine gun out of his pocket.
Now if he was wearing bulky clothing with wires sticking out and yelling "Die, infidel!", he might have had a better case.
Tree cops have no balls cause they are all nuts !
Cincinnati sent a homeowner to the slammer for shooting a punk that had been threatening the homeowner. The deceased came up onto the man's porch and reached behind him saying he had what he need to take care of (the homeowner). The shooter had video surveillance installed because of his fear of the other and that video was used to convict him because no gun was produced by the deceased ( turns out either he didn't have one or (somebody made off with it,IF it existed.) Guns disappear from shootings more often than you might think if a criminal sees a chance to acquire a "free" gun.
