Great idea. While you're at it, get some matching badges, hats, and drive an auctioned off crown vic. Then you'd be really tacticool!
One of the main points of this open carry moment is to communicate the idea that carrying a firearm is NORMAL and that the people that do it are NORMAL. Wearing a uniform to set you apart from everyone else is not only unusual, but it also implies that you essentially agree with the anti's.
Wear your gun, be yourself, mind your own business. No more, no less.
