content: Even one 9mm round would have shut him the fuck down.  The 9mm is WORTHLESS against fully grown groids. In Ferguson Missouri, Darren Wilson had unloaded five 9mm rounds into Michael Brown, which didn't even faze the groid, and it was only sheer luck that the groid yanked the patrol car door open, and bent down to start lunging into the car to grab Wilson, which forced the groid to expose the very top of its skull, and Wilson fired his final 9mm directly into the top of that skull so as to kill the groid once & for all [which was a helluva nice shot, under life-threatening circumstances, with the adrenaline & the testosterone dialed up to "11"]. If it weren't for the act of lunging into the car [thereby exposing the top of the skull] - if, instead, they both had been standing, outdoors, and if Wilson had been forced to continue unloading those worthless 9mm BB pellets into Michael Brown's torso, then Wilson would have run out of ammunition, and the groid [plus its groid posse] would have beaten Wilson to death. At a very bare minimum, you want a rather hot* 10mm round when going up against an adult groid, and if there were such a thing as a 44 magnum Glock, then that would be the gold standard.  From the likes of Liberty or Underwood or Buffalo Bore, in excess of 700 ft-lbs at the muzzle [compared to the 200 to 300 ft-lbs of a typical 9mm round].
