It's unconstitutional, un-American -- and it might hurt, rather than help, the FBI's effort to stop real acts of terror.

The U.S. Justice Department is considering a change in the grounds on which the FBI can investigate citizens and legal residents of the United States. Till now, DOJ guidelines have required the FBI to have some evidence of wrongdoing before it opens an investigation. The impending new rules, which would be implemented later this summer, allow bureau agents to establish a terrorist profile or pattern of behavior and attributes and, on the basis of that profile, start investigating an individual or group. Agents would be permitted to ask "open-ended questions" concerning the activities of Muslim Americans and Arab-Americans. A person's travel and occupation, as well as race or ethnicity, could be grounds for opening a national security investigation....

If the aim is to identify al-Qaida operatives or close sympathizers in the United States, racial profiling is counterproductive. Such tiny, cultlike terror organizations are multinational. Richard Reid, the shoe bomber, is a Briton whose father hailed from Jamaica, and no racial profile of him would have predicted his al-Qaida ties. Adam Gadahn, an al-Qaida spokesman, is from a mixed Jewish and Christian heritage and hails from suburban Orange County, Calif. When I broached the topic of FBI profiling to some Muslim American friends on Facebook, a scientist in San Francisco replied, "Profiling Muslims or Arabs will just make al-Qaida look outside Islam for its bombers. There are many other disgruntled groups aside from those that worship Allah."

It is a mystery why the Department of Justice has not learned the lesson that terrorists are best tracked down through good police work brought to bear on specific illegal acts, rather than by vast fishing expeditions. After Sept. 11, the DOJ called thousands of Muslim men in the United States for what it termed voluntary interviews. Not a single terrorist was identified in this manner, though a handful of the interviewees ended up being deported for minor visa offenses. Once it became clear that the interviews might eventuate in arbitrary actions against them, the willingness of American Muslims to cooperate declined rapidly, and so the whole operation badly backfired.
