It's a frame issue honestly. The Prager argument that schools these days have gone soft or whatever is largely based on lies and mischaracterizations, but there are some real policies like zero-tolerance bullying policies which are supposed to shield schools against legal liability. Anyway, ceding the frame to Prager and just saying "pop tart gun suspension is silly because of real school shootings" kind of loses the argument right there.

Your primary school experience is pretty much the same as mine in the northern US. University campuses almost all ban guns so your security professor would have had to bring in an airsoft rifle.
