BIOMETRICS WON’T CATCH DISPOSABLE TERRORISTS – George Jonas – Benador Associates:

There may well be terrorist moles flying or servicing passenger and cargo jets in Western countries, waiting to be activated for a suicide mission. Some may be pilots or flight attendants; others may gain access to restricted places as mechanics, ground crew, baggage handlers, caterers, or cleaners. The papers of such infiltrators are in perfect health; the sickness is in their heads.

As Bruce Schneier points out, the phrase “disposable terrorists” has a disturbing ring to it. How do you defend against someone who has opted out of life?
