I never try to get someone to carry a gun that has not expressed interest in learning to handle and carry a firearm concealed. If someone asks for my help to acquire their license or have me teach them how to shoot, I gladly offer them a friendly hand. Otherwise, I say nothing. Not my job.
I came to the conclusion after working in a gun store years ago, that while its everyones Constitutional Right to own a firearms, about 50% all the guns I sold were to people that actually SHOULD have a firearm. Had a customer that bought a gun from me....did the three day Brady wait, came back to the store, did the background check.....and he proceeded to take the gun out of the store out into the parking lot and put a bullet in his brain. I had a hard time selling anyone a gun after that one.
There are a lot of people walking around every day with a gun on their hip that have neither the willingness to train with a gun to become proficient, or will never have the mindset to use that gun in self defense. And I still have not met too many 21 year olds that can handle the huge responsibility that comes with firearms ownership, much less concealed carry around others. Of course there are exceptions to my generalizations, and I apologize if I sound down on the maturity of the younger folk. You can't put the bullet back in the gun and hit "replay".
The other side of the coin is the "loose cannons" that are just chomping at the bit to "get their gun off", and these guys and gals scare the crap out of me. You know the type I'm talking about. We all do. Chances are these type have already acquired their firearms and have their CCW. Hopefully they mellow before something bad happens.
