I'm an LEO, and I can obviously carry whatever way I see fit, and well, you'll very very very rarely see me carrying open. It screams "SHOOT ME FIRST" and I certainly do not put a badge on visible. All that does is scream "COME ASK ME FOR DIRECTIONS" or "I'M A GOOD WITNESS, SHOOT HERE..."
So when I run across these type badges, I wonder about the sanity of the people wearing them. It blows my mind.
For your own good, conceal. In most states, non-LEO's cannot carry into govt buildings...Well, even if you can and you have to put a star on, just don't do it. The chances of justifiably using deadly force in a courthouse for example is very very low.
But the badge, leave it at home unless you're someone who was given a badge when you were sworn in.
