It's well known that the Columbine kids (Eric Harris and Dylan Klebold) were heavy drinkers. One of them was nicknamed Vodka, and they frequently listed one of their hobbies as "getting drunk and going bowling." There's scores of material on the Internet that features them lamenting about the harsh treatment they received by their classmates, and I can just picture them taking shots of vodka inbetween rants. If they had picked up a joint once in awhile, it might've lessened the hatred and anger that led to the shootings. The same goes for Kip Kinkel and Seung-Hui Cho. Thoughts?
