No, not Nessie-celery. And frankly I don't know that it would change anything.Keep in mind that lots of Americans—and perhaps a majority of American shooters—are taught to shoot and safely handle firearms in childhood, long before they can own guns. Indeed this is something you must do if you’re being a good parent. There was an interesting news story awhile back, I think it was about single moms or young parents or something, who were very conscientious about keeping the guns locked up and hidden away from their kids; when the journalist asked the kids though, all of them knew (a) mommy has a gun, and (b) where she keeps it. It’s impossible to keep stuff hidden from tiny humans who basically spend all their waking hours looking for stuff to mess up; they figure out how to get to the guns sooner or later, so it’s best to satisfy their curiosity and teach them what to do if they find one. The NRA—yes, the terrible horrible no-good very bad NRA—has very strict guidelines for familiarizing children with firearms (Stop! Don't touch! Run Away! Tell a grown-up!). At any rate the sort of training people get from growing up around guns, and being indoctrinated with the safety rules, is much better than what can be learnt in a few hours of class time.For adults, most people go to a range to rent a gun before buying one, and at least in California, novice shooters have to show the range master how to safely handle the weapons they're going to be using. One time I saw a goofball strut in with some friends, say he was very experienced with guns, and ask the salesperson if he could rent some. She handed him a safe gun and a snap cap, and asked him to chamber then clear it. Clearly not knowing how, he fumbled about and swept everyone in the store, so she barked at him to stop and refused to rent him anything that day, but gave him a flyer for the regularly scheduled beginner class. Obviously this did not impress his friends but that is the way it goes. People who shoot guns are fanatical about safety and you don't need to legislate the instinct for self-preservation into them. New shooters will invariably ask to be taught the basics, and either way experienced ones will make sure they learn them.
