The bomber was apparently not searched...at all. This is in Afghanistan, no less. The CIA let a complete stranger walk into a 'secret base' and blow himself up. As JammieWearingFool points out in his post, though, at least one Administration official finally used the word terrorism. I guess that's some kind of progress.
But where have we heard of this sort of thing before? Starting to see a pattern develop vis-a-vis Muslim bombers and the Government's security mindset? If someone had searched Pantybomber, he would have been caught. If someone had searched this guy, he would have been caught.
Lesson: search Muslims, find bombs. But apparently our government hasn't figured this out yet. It probably needs another 18-month-long-and-horrednously-expensive "study" to confirm this.
