In the delusional world of the NRA's leaders, people can be divided into good guys and bad -- and the good guys never commit violent acts. In that world it follows that we should simply arm the good guys so they can shoot back at the bad guys. For the NRA, this "logic" applies just as well to teenagers as to adults. Back on planet Earth, we understand that far too many 18 year olds who appear to be "good" actually will do some very bad things, and creating a constitutional right for teenagers to carry concealed weapons is nothing but lunacy.
Two summers ago, I blogged with great concern about a statement made by Justice Scalia in the Supreme Court's landmark Second Amendment opinion, District of Columbia v. Heller. Since the Heller decision, many gun rights commentators have used Scalia's construct to link the need for unfettered access to firearms with a right to engage in political violence against the Obama administration. Now, the same five-justice majority as in Heller determined that the holding applies to the states.
