In KY, a CCW permit holder is not required to advise an officer that he has the permit or is armed upon being stopped. Many do however because they know that should an officer discover this on their own, the reaction will probably be altogether different than if they are up front about it. Reading through this thread, they may determine that this belief may be in error (especially after reading Joeyd6's response).
Playing devil's advocate for a moment Joey, shouldn't you be using the same tactics with someone who claims to be a LEO? Anyone could claim to be a LEO and there have also been lots of actual LEO's who have gone off the deep end or ones who kept department ID after being let go. If the name of the game is officer safety (at all costs) then it shouldn't matter who is at the other end of the firearm.
Anyway, my policy when presented with a CCW permit is to ask for them to tell me where the firearm is without pointing or reaching for it. I can quickly verify if the permit is active or temporarily/permanently suspended due to a domestic violence order or other reason. If it's not, then I continue with the traffic stop. Of course, many things could affect this situation. The person's attitude, the type of infraction, the area of the county we may be in, etc. In my opinion, it's not the person who tells me there is a firearm in the vehicle (when I never would have known otherwise), that poses the biggest risk (note I did not say poses any risk).
I think everyone should use whatever method they find makes them comfortable. I, and no officer I know, would ever presume to tell another officer what is appropriate when it comes to officer safety issues. The above is just my personal take on the matter.
