So I briefly read through this entire thread and come to the conclusion that:
This morning he made this thread before he left for school, very soon after newgrounders contact authorities to try and stop him, he was stopped before anything happed, and is now in custody. That is about it. right?
I didn't know the guy on the BBS, but this would have been insane if he actually got to do it (or if he was ever really going to do it.)
Imagine how terrible it wold have been if none of us did anything.
"Evidence shows that he actually posted what he was planning on doing on the Internet an hour or so before leaving. The users of the site all laughed about it and seemed to have a good time, and did nothing to contact authorities"
Yikes, good job team, we saved innocent lives!
