16 out of 21.
Last I checked, the mil. does not put forgrips on they're general issue M16s. Dead give away.
I would maybe have less of an issue with cops using miltary grade stuff if it was actually military quality, meaning duck tape on their stocks and no tacticooling.
But bridgy has it right, cool the "war on drugs" and use civilian junk with an eye to public image. If the need the armored vehicals, let 'em have stripped former miltary gear, armour only. Truth be told, they'd be MORE functional with semi auto and adapted civilian gear, as they're purpose is to stop crime, not kill the enemy.
I can think of NO reason for a LEO to need a freeking belt fed weapon.
