It's been my experience that once you let that knowledge out you lose all control over it. Right after I got my CHP I made the mistake of telling a friend who proceeded to share that information with a third party that I wouldn't have told. He actually piped up in the middle of a conversation the three of us were having with "Smoke's carrying a gun right now." Luckily the comment went right over the third guy's head.
I also made the mistake of telling another friend from church who then proceeded to tell everyone in his circle because he thought carrying guns was "cool" and that knowing someone who carried a gun made him "cool" even though he never got his CHP. When I explained that I had shared that with him in confidence and would rather he didn't pass it along he told me it was better that people knew because they'd feel more "comfortable". I've avoided him since.
My wife told our daughter who also dropped it into a third party conversation in the form of 'Don't mess with my mom man, she's strapped." although she did have enough sense to listen when her mother asked her never to do that again.
