Just want to throw out there that a lot of the info about bullying at Columbine was overblown in early reports. Harris and Klebold were not bullied in the same way that Taylor was, certainly, and Harris, at least, was a straight-up psychopath, so I'm not loving the parallels being drawn here (http://usatoday30.usatoday.com/news/nation/2009-04-13-columbine-myths_N.htm). Bullying is certainly a problem for other reasons, but I am not sure why this show is pushing the bullying --> school shootings line, when that's not really borne out by evidence.
