...main criticisms of the scanners, which have already been installed at 19 airports in the U.S., is that they cannot detect low-density materials such as powders, liquids, thin pieces of plastic or anything that resembles skin. Nor can they detect any explosives concealed internally. Some politicians and aviation experts have questioned whether the scanners would have detected the powder that Abdulmutallab carried on board Northwest Flight 253. Ben Wallace, a British Conservative Parliament member who was involved in a defense firm's testing of the technology, said over the weekend that the scanners probably wouldn't have picked...
...Experts say the undergarment bomb probably would have shown up on the new generation of whole-body imaging scanners that are chiefly designed to detect explosives. These devices, using millimeter waves or X-rays, generate a picture so detailed that the officials reviewing them are located elsewhere for the sake of passenger modesty. But Amsterdam's Schiphol has only about 15 of these machines serving some 90 gates, and they are used on a voluntary basis only on short-haul flights within Europe. That's partly because the wave scanners are costly - they sell for $180,000 - and partly because...

Only about 40 millimeter-wave devices are in use, at 19 U.S. airports. Standard magnetometers, which are used at the vast majority of the more than 2,000 checkpoint lanes nationwide, can detect metal in guns and knives but are worthless against explosives like PETN...
...truly international catastrophe: the tsunami struck 13 countries, killing 226,000 people of 40 nationalities. Five years later, a first-time visitor to the worst-affected countries - Indonesia, India, Sri Lanka and Thailand - might find the wave's terrible path hard to detect, thanks to a multinational, multi-billion-dollar reconstruction effort. Across Aceh, thousands of houses were built with foreign aid in what were once wastelands. In Banda Aceh, the provincial capital, new homes surround a 2,600-ton ship pushed a mile inland by the Tsunami. It is now a tourist attraction. (See TIME's photo-essay...
...Coulson argues, in fact, that one reason so many terrorism-related cases popped up in 2009 was the improvement in the ability of U.S. authorities to detect plots. It helps too that ordinary Americans have grown more alert to the danger. "More and more people will call in the police or FBI when they see something suspicious going on," he says...
