It's a political stunt, and has me a bit mad
. It means the cop has "more reason" to issue you a citation, or whatnot. Odds are, cops don't enjoy knowing that the person they're talking to is armed--even if it is entirely legal. They'll probably write you up for the dumbest of things, and/or have no mercy, depending on if you get a pro/anti cop. I may be overreacting just a wee bit, but I'd be very irritated. Most people don't like how I look to begin with, I don't need them to have another mental strike against me.
