Al-Qaeda practises beating body scanners

A body scanner at Amsterdam's Schiphol Airport would not necessarily have detected the explosives which the would-be syringe bomber, Umar Farouk Abdulmutallab had sewn into his underwear. A Dutch military intelligence source told De Telegraaf newspaper that Al Qaeda has its own security scanners and has been practicing ways of concealing explosives.
The terrorist group has even carried out test runs at smuggling explosives through European airports, the paper reports.
On Monday Schiphol's operational manager Ad Rutten said the explosives carried by the 23-year-old Nigerian Abdulmutallab may well have been detected had he been scanned by one of the airport's 15 body scanners. Schiphol was the first airport to run a trial of body scanners, which use sound waves to see through passengers' clothing. At present the scanners are only an optional alternative to the conventional metal detector, as European privacy laws prevent them being made compulsory.

Doesn't exactly support the assertion, does it.
Any system can be defeated. That's why its important to have a multi-layed system, using technology, observations, and physical searches. The biggest threat to our security systems is not Al Qaeda, its the political correctness of the political class.
