Allows teachers to carry, doesn't force them to carry, which seemed to be what Trump was saying, right?
Exactly. They want to cover the very likely scenario of a teacher protecting the children in their classroom. There's usually one relatively small door through which the shooter has to enter. No one's supposed to be Rambo.
Look, I've been a kid in school classrooms, I've been in classrooms with nasty little fuckers who wouldn't think twice about taking a gun.
Yes, you're so ******* concerned about children getting shot up. But they're not getting shot up in the UK, or France, or Germany, or Spain, they're getting shot up in the US, and the only difference between those countries in this regard, is the easy availability of guns in the US.
