High noon in year 9?

The default position of the pro-gun lobby in the US is that the best answer to a bad guy with a gun, is a good guy with a gun.  In other words, a shoot-out.  So perhaps it came as no surprise that Trump and the NRA's answer to the recent school shooting over there was - arm the teachers.  We over here find it difficult to understand why this idea takes precedence over what to us is the more logical concept of restricting the availability of firearms, but there you are.  Can't say the thought of loaded guns being in school buildings as a matter of course fills me with anything other than foreboding. Don't think I'd want to be a teacher over there!
