One was. But you say "kids", plural. Was Dylan Klebold being medicated?
Assuming they were, what's your point? Are you saying the parents were already dealing with the issue, or are you saying that the medications caused the killing spree?

I remember that both wer on drugs. They reportedly were laughing their asses off while doing the shooting. Sounds to me that the drugs were working just fine. /sarcasm
