I made the prediction that there will be a lot of school shootings on another site because Clinton's gun ban expires soon and Bush will need some excuses to not only renew it, but to expand it as well.
Nothing bans guns faster than knee-jerk reactions after a good, school shooting. It never fails.
Germany wanted to ban some guns around a year or two ago and a mass school shooting conveniently happened.
Also, almost every shooting involves kids who use mind-akterning and/or mood drugs like Prozac which in the wrong amount can make people very violent. I'm going to look into some research somebody did on the topic withing the next month.
