I agree with the cable news aspect you guys mentioned, it's definitely used as a ratings driver, which could end up enticing kids to become infamous. On the other hand, the internet is just as big of a problem and there's not much you can do about that. All this info about these shootings is readily available on the web, then you can go deep into those various reddit threads, chats, whatever else there is that I don't even know about it. Kids anonymously encouraging others to go out and act on their fears. I guess as parents you can try to police a child's internet use, but we all know that won't happen in most houses, especially when the kids knows 10x more about the web than the folks.
