I think it might also reduce the rate of gun accidents (teach gun safety, remind importance of gun safes, ammo storage, etc.), which would be nice to have happen.  Plus, you'd have much better shooters, so in cases of defense, the job gets done better.  Lots of people own guns and haven't even taken a single course.  Heck, throw in discounts for CWP's, since the person already paid to be partially trained. 

Oh, I forgot...one other thing.  Get caught with a gun and no card, and it's mandatory 10 or 20 or something like that in jail, no parole.  Likely clean up a lot of that inner city garbage.

Maybe it'll help protect the law abiding citizen while we get rid of the riff-raff?

Oh, no apology necessary.  It's board-talk...lots gets left out, misinterpreted, confused, etc.
