This is insane! Why on earth would you people, in the wake of Parkland (and every other shooting that has happened) choose to LOWER the age at which young people can buy ANY gun? I teach high schoolers. 18 is NOT old enough to be entrusted with any kind of gun, much less something that you can hide in a backpack or under a shirt. Teenagers, especially males, are just getting their feet under them. They are surging with testosterone. I have seen the way many of them deal with the challenges of being teens WITHOUT access to a gun. It is a terrifying thought to imagine what will happen WITH easier access to a gun.
