I went to 12 years of Catholic schools in the late 50's and 60's. Like most kids in my school, I was from a very large family. Basically, my parents were so busy that I was ignored. I was in so much mischief that 10 books couldn't tell the story. I loved to blow things up, make crude guns, burn stuff, steal stuff, etc, etc. My parents were clueless, and, I never got caught! Not once. I had a lot of cops chase me, but not one ever got me. One note, however, we never hurt anyone or anything. But kids have been behaving badly for a long time, and, to various degrees, and for different reasons, always will.
Still, not the same.
Ryan and Dylan had been arrested for their actions. They had been undergoing therapy for their problems. One of them was medicated. Their threats were public, and their parents were aware of the threats. The threats were serious enough that they had been brought to the attention of the authorities.
Amazing that the parents are such experts on how the school was full of bullies that picked on their kid, but unaware that their children were preparing large propane tank bombs.
