Virginia Tech fallout

So a straight A kid at Cary-Grove high school got in trouble for a creative writing assignment that apparently was a bit dark for the school administration. I understand the cloud of paranoia the country rests in after the Virginia Tech shootings, but I wonder how far we will let this go. Anytime there is a disaster I worry what new civil right will be in danger of becoming a fond, obscure memory. This seems to happen after a school shooting where we take a closer look at kids. But then we seem to forget after a few weeks and another tragedy happens and then we pay attention again. Perhaps the key here is to pay attention all the time. I do not advocate stifling someone's creativity no matter how dark. I'm sure Stephen King seemed like a possible serial killer when he wrote things in high school, but nobody suspended him. The question then becomes when do we intervene? If we don't figure this out, we are in danger of sliding into a minority-report like scenario where we punish people for possible crimes they are going to commit.
