Unc linked to a pic of an NYPD cop in full ninja garb on the New York subway, apparently a response to the self-immolating goatherds in the Moscow Metro.
I don't know what a dude with a carbine is supposed to do in that situation, except maybe make the taxpayers feel better by getting blown up along with them in a show of solidarity.
I'm also kind of curious just how many hours of training the guy has and how much time he spends a day with a carbine in his hands. A lot of things like muzzle discipline come down to ingrained rote familiarity, which is something you're just not going to get when you draw a carbine from the arms room once every ninety days. A crowded subway car is maybe the trickiest place I can think of to safely lug a longarm, much less deploy it effectively.
