Ignoring TAB's stupid remarks....
I've carried in five states and am currently licensed in three. Back in the day, we could carry openly on the streets of Northern California as well as in the state of MI. Granted this was the seventies but there was no blood running in the streets then any more than there is now. There was also no concealed carry laws.
Basic safety courses would be probably required but there are those in the industry that believe that responsible carry requires more training than that minimum. I would venture that most of the proponents of that training are those that make a living teaching it!
Personally, I've been trained by the best, my father and my Uncle Sam! The other courses I've been required to take in MI, CT and MA were essentially a way for someone to take 50 or 100 bucks from me and sign a document. Useless!
We can get there, but who's going to set the standard? If the Feds do it, it won't work, remember the whore house analogy?
No easy answers...
