Well sure, when you go to a gun free zone of course the shytbag low life criminal is going to have a fun slaughtering helpless school children and defensless teachers who all they can do is jump in front of bullets and die with no concept of self defense.
But speaking of knives, its easy....or you can use a pressure cooker throw it in a class room, run over kids with a truck, use swords with skill and slaughter plenty. Its not hard especially when government promotes teachers being pansy asses but its not their fault because most of them grew up in the public school systems where your taught to be dependent on others rather than being a rugged responsible individual capable of defending themselves against bullies.
But back to knives...here is a few, just in China of recent times.
