Why is this WTF? Seems sensible to me.

Surely that is what your active shooter drills teach you Yanks, run, hide, call the police, fight if you have no other option.

Hell your police run and hide when there is an active shooter.

Even in Freedomland most people don't carry firearms. What else are you realistically going to do if someone has a gun except run or hide? This seems like a total non-story. Especially in a country with ~30 firearms homicides per year (which is about 1% of the per capita rate in the US).
