But many children have died in China in recent years in similar knife
attacks at schools... By statute they and other locations have become
relatively safe places for madmen to cause mayhem.

Right. Let's use that as a reason to equip everybody including
teachers with firearms.

The problem with guns is that you can't outrun a bullet and it's
pretty hard to fight off someone if they're aiming a gun at you. With
someone holding a knife, you might be able to stay out of their reach
or at the very least, have a much better chance of fighting them off.
