No surprises makes everyone safer.
If you reach for your bill fold and his parter sees a gun on your hip... I would rather not have 40 sw bullet rattling around in my cranium.
My God, why do we think cops are that trigger happy? So they see a gun. Lots of people have guns. It's a long way from on your hip to pulled and pointed in your direction...
And why would cops think everyone wants to shoot them anyway? Everyone who carries a permit is willing to kill a cop to get out of a speeding ticket?
Are cops that jumpy at a shooting range too? Everyone is carrying a gun....
