well, I haven't found anything but I will tell you a story my web design teacher told our class.
In our school, there was a kid in his class. I don't know, maybe he finished his work or he was bored but he got on yahoo and asked how to build a bomb. someone replied back "why?" and he said "I want to blow up a school". It was a stupid joke but eventually homeland security found and and did a full out investigation on the kid.
Insanely stupid, some kids these days...
