Gun Control & RKBA

The reason they don't have mass killings has nothing to do with the availability of guns. It has to do with a mono-racial, nationalistic, communally-minded, and shame-based culture. It's for the same reasons that my neighbors would knock on my door to let me know if I put my trash out in the wrong kind of bag. It for the same reasons that families of people who are sent to prison -- unless they're yakuza -- will often disown and disavow the them: "I have no son." It's for the same reasons that corporate executives who are caught in malfeasance will often commit suicide.

This is not to say that Japanese citizens don't occasionally go off the rails. The Aum Shinrikyo cult in the 1990s committed a poison gas attack on the Tokyo subway system that killed 13 and sickened more than 5,800. The cult had purchased numerous military weapons from rogue elements in the former Soviet Union and were attempting to purchase uranium to construct their own nuclear weapons. They actively recruited advanced students in the sciences, using a combination of psychedelic drugs and sexual favors to seduce them into joining. They launched the Tokyo attack prematurely, after attracting police attention for one of their attempts to test their chemical weapons in a Tokyo suburb. It's chilling to think what they could have achieved if they had had more time to plan and prepare.
