This is why the Teachers Union doesn’t want armed teachers: They would probably have to shoot some of their students in self-defense instead of letting themselves be assaulted.
I wonder why the NRA and other gun supporters don't make this point? How many defenseless people, mostly women, have been murdered by men who didn't use a gun? The number is vastly greater than the numbers of people killed in mass killings by shootings like the one in Oregon. The gun grabbers never mention that.
