The drumbeat for racial profiling grows louder in New York City (thanks, DesiDancer):
Two elected New York City officials say Arabs should be targeted for searches on city subways. They claim the NYPD has been wasting time with random checks in its effort to prevent terrorism in the transit system… The New York Police Department said in a statement that racial profiling is illegal, of doubtful effectiveness and against department policy.

… they are most likely to be young Muslim men. Unfortunately, however, this demographic group won’t be profiled. Instead, the authorities will be stopping Girl Scouts and grannies… commuters need to be most aware of young men praying to Allah and smelling like flower water. [Link]
Even Tunku Varadarajan of the WSJ came out for profiling desis:
I find that I am–for the first time in my life–part of a “group” that is under broad but emphatic visual suspicion. In other words, I fit a visual “profile,” and the fit is most disconcerting… one must be satisfied either that profiling ought to be done or at least… that it isn’t something that “ought not to be done…” The practice cannot be rejected with the old moral clarity. The profiling process is not precisely racial but broadly physical according to “Muslim type…” [Link]

I’m pretty sure the 7/7 bombers did not leave the house all gulab attar-fabulous. It’s a practice more Arab than Pakistani, and the smell would have drawn too much attention. Racial profiling, the knee-jerk reaction to terrorist attacks on public transit, is a fool’s game. Instead of detecting inaccurate signatures (black, Arab, South Asian), the goal must be to detect behavior (carrying a bomb). The goal is accuracy. Otherwise you let deadly attacks succeed while wasting massive amounts of resources searching ordinary people.
The arms race between black hat and white hat has deep analogues in the military, the human immune system, antivirus tools, firewalls, spam filters and so on. In realm of computer security, behavior detection has utterly buried signature detection in terms of effectiveness. Signatures are trivial to spoof once you know what’s being looked for. Most viruses, worms and spam now mutate with every attack, it’s designed in from the beginning.
On 7/7, Al Qaeda switched from using Arabs to using Pakistanis and a Caribbean. Not two weeks later, they switched to using Africans. The pool of Muslim phenotypes is enormous; they can tap Chechens, Uzbeks, Filipinos, Indonesians, Chinese, Malays, white converts, black Americans, red-haired Kashmiris, blue-eyed Afghans. This is why the NYC mayor says the NYPD will use a true random sample instead of racial profiling. It’s not out of liberal fuzzy-mindedness, it’s because they’re being hard-nosed about saving lives. A race-based approach fails completely. It’s suicidal to rely on it.
