For one very obvious reason: American kids have never before committed suicide using terrorism vests. Whatever this kid was up to, this is unprecedented. That is why it should be enormously interesting to us, perhaps not 24/7.
Who is reporting he had on a suicide vest? It is very possible he wasn't committing suicide but wanted to blow up a bus (a K-State bus) and the bomb went off prematurely.
I don't know who to trust anymore as far as releasing info to us. They apparently have a reason for keeping us in the dark, let's just pray it's because they don't want to spook someone who is already on their radar, and not because they think it's better for us if we remain ...uninformed.
