I worked for awhile in a big-box sporting goods store; we sold one Helluva lot of gun safes.   I think I'm typical in that I have one long gun that isn't in the safe in case something goes bump in the night; the rest of them the typical criminal would have no chance of getting at, and the one that is unsecured would meet any criminal coming in my house.   Seeing me wearing nothing but a Mossberg and a smile is a really bad way to go.

Selling a gun to someone underage is already illegal; what would you do?
