and I can't recall where I read it, but it makes a lot of sense, so I'll paraphrase it . . .
If you're going after the Mafia, you infiltrate store front social clubs in Little Italy.
If you're going after the Irish Republic Army, you infiltrate Irish pubs in south Boston and New York.
If you're going after who ever is leaking information to Israel, you infiltrate Jewish American groups.
If you're going after the Ku Klux Klan, you don't waste your time tracking down African American suspects.
It's not profiling, or bigotry, or prejudice, it's common sense.
Therefore, if we're going after Middle Eastern fundamentalist terrorists, who should we focus on?
