It is long past time to end these suicidal policies. From [1] AP:

PHOENIX - The FBI agent who wrote a memo warning that terrorists were training at flight schools before the Sept. 11 attacks said concerns over racial profiling may have prevented officials from acting on his intelligence.

"If you look at the world prior to 9/11, we were prevented from doing certain things. We were victimized by our own restraints," Ken Williams told The Arizona Republic in his first interview since writing his now-famous memo in July 2001.

Williams' findings were based on investigations of Arizona aviation students tied to al-Qaida. At the time, he recommended the State Department coordinate with the FBI to provide information on flight students from Middle Eastern countries.

His memo was ignored by supervisors until after the attacks, but Williams said it was not a case of incompetence or malfeasance and he never blamed supervisors for the intelligence failure.
