It was reported last year that a terrorist tried (and failed) to assassinate Saudi Arabia's counter terrorism chief by detonating explosives in his anus. That turned out to be merely an underwear bomb attempt, not a surgically-implanted bombing, but the fear of body-bombing remains, at least in the media. In March, Fox reported that "female homicide bombers are being fitted with exploding breast implants which are almost impossible to detect," according to MI5 sources. And now the SITE Intelligence Group has picked up chatter that "Al Qaeda affiliates" are working to match doctors with suicide bombers in search of exploding implants.

According to a translation by terror experts at the SITE Intelligence Group, users of a Jihadi website forum are discussing stitching bombs made of plastic or liquid explosives, such as semtex or PETN, to the abdominal cavity. According to a transcript obtained by The Daily News, one forum member advises that the bomb "must be planted near the surface of the body, because the human body absorbs shocks." Another wrote, "I am waiting for the interaction of the experienced brothers to connect the two sciences together and produce a new kind of terrorism, Allah willing."

The controversial new porno scanners can see under clothes but not through human tissue. So does this mean body cavity checks are the next act in the TSA's Security Theater Variety Hour? TSA chief John Pistole has already promised not to look inside travelers' orifices, and he's counting on security screeners to find the detonators that butt or breast or belly bombers would need to keep outside of their bodies. "You have to have some external device to cause that initiation," Pistole said earlier this month, "That's what the advanced imaging technology machine will pick up: any anomaly outside of the body."

Other experts aren't convinced the TSA is prepared for the coming wave of butt bombers. "We have nothing in our arsenal that would detect these bombs," one counter-terrorism expert told Jeffrey Goldberg at the Atlantic last month. "My assumption is that a bomb carried onto an airplane in the anus could be removed in the bathroom and detonated clear of the body. You're dealing with a thin-skinned airplane, so even a detonation of a pound of explosives in the anus could punch a hole."
