Training should be required.
I suggest that basic firearms safety and handling should be taught in high school along with a civics class (do they do those anymore?). Throw in an economics class, too. Not Home-ec (do they do that anymore?). I don't care about baking cookies or sowing, although perhaps teaching how to scramble an egg and prepare a healthy meal that didn't come from a drive-thu is a good idea. More like balancing a bank account (almost said "Checking" account, but that might confuse the youngsters as they try to figure out what a check is), understanding credit and taxes, basic investing knowledge, etc... Stuff that everyone should know to be at least modestly able to live adult lives.
So... yeah. Mandatory training. In high school. So kids can turn into adults and be able to immediately and safely exercise their rights to self defense.
Like FCS?
