We looked at gun bans in the 90's. You know what they found? Had such a massively minuscule effect on crime and murder rates that the FBI said they were totally worthless. Did nothing to stop mass causality incidents as demonstrated by the columbine highschool shooting, as well as others.
Oh, you mean that high school that had armed guards? That one?
"But Squiggy, they were ordered to stand down."
I don't give a fuck. They had armed guards, just as the NRA is suggesting. The failure of the armed guards FOR WHATEVER REASON is ample evidence that your idea is idiotic.
Now, blame 20 year old video games as your masters tell you.
