1 Blind profiling is silly, and leads blind spots in one's defense strategy. But then, it also seems to work to a certain degree: Maybe the reason [drug smugglers] switched from one-way tickets and two bulky suitcases was that law enforcement got wise to those habits, so the smugglers did the equivalent of what the jihadis seemed to have done in London, when they switched to East Africans because the scrutiny of young Arab and Pakistani men grew too intense. Giving extra scrutiny to young Arab and Pakistani men has value but only if it doesn't make you blind to all else that moves. At some point, I fully expect the jihadi's to attempt to recruit blue-eyed, blonde-headed, Northern European women simply since they so don't fit the "profile".

2 Remember: anyone can have blue eyes or blonde hair if he/she wishes.
