I agree with the author on Klebold being responsible for his own actions, but if I were to play the blame game I would look at Hollywood and the FBI/ATF.
The doomed duo clearly copied the lobby scene from 'The Matrix' where Neo and Trinity kill all the guards and reinforcements in gravity defying style, all set to a rock beat.
The first time I viewed this scene I was very impressed, but since buying the DVD and watching it several more times I can't get over how corny and stupid it actually is. However, two teenage boys would be awestruck.
Where else could a young man find such vivid images of total control, power and murderous mayhem? The nightly news,of course.
Watching the FBI's RV/Tank tear holes in the Waco home of the Branch Davidians, followed by the fire and extermination of nearly everyone inside must of been a rush to these kids. Something to imitate if you wanted to show your power over others.
The fact that they had planted an explosive(dud) to start a fire in the kitchen and that they had originally planned to attack the school on April 19, same as Waco, but were pushed back a day due to not having the bombs and weapons ready, is evidence to support the theory that they wanted to copy their government's actions.
You can blame Hollywood, but must also blame the parents for allowing him to watch such drivel.
It's a stretch to blame FBI/ATF. Blame clintbilly and Reno for making it happen.
Nightly news will cover the carnage, regardless of administration.
Of course, IF it had happened under a pubbie administration, the GUNS would have been responsible; since it happened under RAT administration, it was a necessary incursion.
They copied a movie that was made after their deaths? That's talent.
