The only thing knowing that you have a CCW tells the cop is that you may be carrying legally. How does that help them stay safe? If you have a CCW you are unlikely to be a threat and may even be an asset if the cop is endangered. He still runs the same risk that the guy with no CCW might might be armed and in no mood to go to jail for an outstanding warrant.
I agree with you and I apologize for not making my statement clearer. The idea of letting the police know is for their benefit, and as another poster stated any police officer who does not approach a situation with the thought that weapons are involved/around(doesn't have to be a gun)is a fool.AWB
Here in Arizona, if I'm stopped by the police and they run a license check on me, they will see that I hold a CCW permit. It's good for them in case I'm driving drunk or talking suicidal or on the wrong end of a high-speed chase. The police deserve to have all the information they can get when dealing with a potential bad guy.
