I hope so. I don't think an incident such as this one will be happening again in Russia soon. From what I understand and have personally seen, Russian parents are crazy about their kids. This is going to hit Russian parents very hard.
Of course, sometimes we are our own worse enemies. We have school districts in CA who indoctrinate their students with Islam in their social studies classes with curriculum written by a woman who is Islamic. We had schools insisting (after 9/11) that students not call the perpetrators of 9/11 "terrorists."
The only good thing to come out of Columbine is people's awareness of terroristic incidents such as this one.
