Your piece is interesting and I agree that banning weapons isn't an answer. I learnt something many years ago, and that was anything can be used as a weapon by those determined enough, I had the opportunity to work in the prison system for a period of time, and learnt that even a piece of paper could become quite a serious weapon. At what point are things banned, first a knife, what about a fork, what about hands, in many respects everything and everyone becomes a level of danger? Thanks
