Was the Colorado Shooting Sparked By Video Game Violence?

How can a teen laugh while he is shooting down his peers?? In the case of Eric Harris, I believe it was because he desensitized himself to all the blood and gore long before yesterday's events took place. This boy was an avid Doom and Doom II player. The Video Game industry better get ready, because the fickle finger of fate is about to start pointing in their direction.

From Eric's profile on AOL.com:
'Hobbies: professional doom and doom2, creator. meeting beautiful females, being cool.
Occupation: part-time worker at a fireworks stand in CO, and DOOMING the hell out of my computer!(playing doom, a lot: )
Personal Quote: when in doubt, pull it out.(computers)-----Shut up and shoot it.----Quit whining, it's just a flesh wound-----Kill Em AALLLL!!!!'

He ran a site on AOL where you could download games he programmed for Doom.
