4. Thomas Watt Hamilton

On March 13, 1996, Thoman Watt Hamilton drove to Dublane Primary School near Stirling, Scotland where he launched an unprovoked attack on a gymnasium full of 6 and 7-year-olds. He shot and killed 16 kids, and 1 teacher, and injured 15 more all within four minutes. Then he turned the gun on himself and committed suicide. Hamilton was described as anti-social, intolerant, and deceitful, and there were complaints about him acting inappropriately towards children. In response to the massacre, Britain passed two new firearm acts, making private ownership of handguns illegal.
