Just about sums it up...

As seen on twitter:

Update:  it occurs to me, if the example of the miserable teacher Arky, who comments regularly at Catallaxy, is anything to go by, you would have to be careful about the mental well being of the teachers being issued guns.

Meanwhile, unsurprisingly, given the American Right friends that he has, I see that Tim Blair thinks teachers having a 9mm pistol is a good idea.    Which leads me to suspect that he has little or no experience with pistol use and no idea about their accuracy, range and lethality in comparison to a dude with an AR15 blasting away.   (I'm no expert, either, but you only need to try them a couple of times to realise their limitations.)  

While it is not inconceivable that a future shooter might be taken down by a pistol shot (most probably, from behind and at close range) - you would think that mass shooting at  military bases might give a hint to gun lovers that more guns in the general vicinity of a shooter's target is no disincentive to the start of mass shootings.    That "Gun Free Zones" encourage shooters is one of the stupidest arguments that the Right grabs.

The nutter not having a gun in the first place is a much more reliable way to prevent shootings.
