So why do I own armor, night vision, black scary guns and shit ton of other military type gear? Because I can. As a free American, I can own anything I want, including a machine gun, a silencer or even what the press calls "a tank"...If you say cops shouldnt have access to military style equipment, then you might as well just say lets cancel the Second Amendment"...I firmly believe in outgunning your opponent whenever possible.
There's a significant problem with this argument. I'm guessing he didn't see it.
