The NRA rails against gun-free zones around schools. The NRA is now advocating that we put an armed guard at every school. Let's briefly hash out the likely outcome of this below the burnt-orange University of Texas squiggly thingy...
I don't want to delve into the "why" of these mass-casualty incidents other than point out that it's "terrorism" when Muslims do it, "gangbanging" when urban African Americans do it and "Mental illness" when upper middle class white people do it....But I'm off topic before I even started.
So let's assume a person is interested in causing mass casualties at a school - because he's a terrorist, a gangbanger or mentally ill. At the urging of the NRA, schools are no longer gun free zones. In addition, schools now employ an armed guard. The person enters the school grounds, parks his car and grabs his guns. He walks towards the school. The armed security guard inside takes note, but of course this person isn't doing anything wrong. Carrying guns in school is perfectly legal.
"But!" you might say "the guard is armed! He can stop this guy in his tracks!". Yes indeed, except the guy has done nothing wrong. And being a terrorist/gangbanger/mentally ill person of at least some mental capacity, the murdered knows where to shoot first - the security guard. The security guard can't defend him or herself until after the shooter takes aim, which would a bit too late to put it mildly.
Now the armed murderer has access to the rest of the school...and the guard's gun so he can get a few more rounds.
This is what the NRA considers a "solution" to the problem. Color me amazed. Or not.
