In Japan no one shall possess guns and swords. Japan is said to be one of the safest societies in the world (Global Peace Index says Japan is 6th out of 162 countries). Dave Kopel of University of Denver says, "Hideyoshi decreed 'Sword Hunt' to ban possession of swords by lower classes. Since then Japanese people have been thinking that control can protect themselves and their society (Taro translates)."
I hear that fewer guns fewer crimes and it seems to me that Japanese people never doubt but believe it blindly, though it can't be cleared statistically. At any rate, I do not want to see people being killed with guns and I believe it's only we ourselves that can make our society safe and peaceful.
Postscript: Hideyoshi Toyotomi struggled to invade the Korean Peninsula and killed hundreds of Korean people. I do not think that he was a pacifist.
