The latest security threat: Butt bombers?

I hesitate to even link to this post, but I just have to: Bruce Schneier on the latest security threat: Butt bombers. (Warning: The post talks about body parts normally more sat upon than regulated by TSA.) I'm actually surprised it took this long for someone to go there, so to speak. If someone's willing to die for a cause, what do they care what they have to do to make it happen? I do doubt TSA will be hiring proctologists to handle this new threat, though.
