These dudes need to be given a free marksmanship training session at a Federal Law Enforcement Training center. Food stamps, Obamaphone, handgun training.
I’ve seen one of these guys in action close up and very personal. They don’t aim—they have a gun in each hand and just spray bullets in the general direction of their target. They will probably never be caught, at least not this time. Chances are they will be the targets next time because you can be sure someone in that crowed knew who they were. That was a 2nd line parade, by the way, a grand old tradition, and it’s a travesty to attack the participants.
