Ummm ... could it be perhaps that there are really not that many terrorist out there? The most dangerous we seem to have captured were a few guys from Detroit buying up cell phones and some loonies in Florida supplied with boots etc. by an agent provocateur. Even the one in London who were supposed to be making the "mix it yourself" liquid bombs seem not to have been anywhere near ready to knowing to make such a device and were still trying - on their own - to figure that out.

Hysteria! We are protecting against a largely non-existent threat. And when a competent bunch comes along, they will not have difficulty penetrating our security charade. Hint: the bombs will not be in shoes or an 80 yo's medication.
