Here is example of a perfect traffic stop from my civilian's point of view...
Officer: I clocked you at XX mph in a YY mph zone. May I see your license and registration please.
Me (handing him my license, registration and carry permit): Here you are sir. Just to let you know, I have a concealed weapon permit and I'm carrying right now.
Officer: Where is your gun?
Me: In my back pocket.
Officer: Well, just let it stay there (hands me the speeding ticket).
