Terrible advice. In Colorado if you have a gun, shut up. The cop doesn’t care unless you are handling one or pointing it at him. Simply let him do his job and stop trying to be a self-centered idiot bragging that you have a CCW or that you are “a responsible citizen exercising my right to carry in a vehicle”. He doesn’t care. Just don’t go making an issue about it.
P.S. In Colorado we are not required to tell the cop about a CCW, hand it to him, or tell him about any firearm unless he asks. Hell, he can go back to his vehicle and find that out pretty quick. It is totally a non issue and cops don’t appreciate someone trying to make it an issue.
Interesting advice.
