With the private ownership of handguns almost impossible in Japan, whackjobs who want to go down and take a bunch of innocent people with them usually resort to swords and knives. In the wake of the tragic Osaka School Massacre of 2001, Japanese school teachers consulted with the police to answer the question: if a knife-wielding maniac gets past the school gates, how can we hope to control them?
