...extremists operating from Yemen present the military with precious view good "aim points." In the old days, the enemy had airfields, early-warning radars, ammo depots - even big defense and intelligence headquarters - that could be destroyed from the air. A general could stride manfully out to the Pentagon podium, wave his pointer like a magic wand at a map where little explosion drawings had been inked, and gleefully tally up the destruction.

Experts say that more aggressive safety protocols might have uncovered Abdulmutallab's alleged plot before he had the chance to botch it with a bum detonator. Full-body scanners might do the trick, but they have their drawbacks. The ACLU has condemned backscatter X-ray and millimeter-wave-radar scans as the high-tech equivalents of strip searches. Furthermore, "every technology can be defeated one way or the other," says Vahid Motevalli, who studies aviation security at Purdue University...
...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...
...five years after the bipartisan 9/11 commission recommended that Congress and the Transportation Security Agency "give priority attention" to screening passengers for explosives, the practice remains overwhelmingly the exception and not the rule. 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...
...Karachi, the largest city and commercial center in the nation. As the death toll mounts, the country's political leaders have united in their condemnation of the attack. It was the third such assault in Karachi in as many days, crushing the city's hopes of evading the current wave of bombings, deepening fears of further sectarian attacks and underscoring the militants' deadly ability to strike seemingly anywhere at any time...
