This crap doesn't happen in any other country but America. In Japan when someone goes crazy they just kill themselves or make a suicide pact with someone else, they don't kill innocents. In China when someone goes crazy... oh wait they can't - only the government can kill people. In Canada when people go crazy.. I don't know what the do - but they don't kill innocent random people even though they have tons of guns. England the same. Almost all of Europe.
Actually these public shooting and or killing rampages are hardly unique to the United States. More prevalent, probably yes, but not unique.
I recall a recent incident in Japan where some guy actually went on a knife/machete rampage and killed like eight people, wounding a dozen others. Canada has had incidents, as have Europe (France...Germany...UK).
I spent hours researching this in 2002 or so and posted my findings in a discussion but I tried to locate it in the archives and its nowhere to be found. Not going to do it all over again, but the info is out there for those who have a few hours to kill. The list was pretty extensive.
In Israel, allowing members of the public to train for and carry guns proved to be very effective, with several would-be Palestinian terrorists shot before they could do anything more than wound or kill a couple people.
Of course, the Palestinians simply resorted to bombs instead of guns. Easy enough to make, conceal, and deliver. Ban guns, and we will be asking "how to prevent school bombings?" Where there is a will...
