There are a lot of retards out there, it's unfortunate that a few showed up to your match. Cops are people (and not hardened infantry), and the fact that almost no one in general can shoot really well simply carries over to that field like any other.
Overweight guys showing up with egos and tactical gear immediately have their douche card vigorously punched on visual, and in my experience they're exclusively not police, military, or anything remotely requiring that style of gear. It's not even remotely necessary for shooting matches regardless. Only thing left after noticing it is to crush their pathetic shooting and rub it in as much as possible. They'll either shut up and learn or go the fuck away forever, and either one is a happy ending
Good on you for going out with your buddies and daughter and actually having a good time. You're also a more humble man than I, I'd be taking pictures and posting that shit all over Doodie Project
