Question is, how do you profile "Muslim?" Plenty of gents (and ladies) fit the bill of "radical Islamist" without fitting the physical description that is the stereotype of so many Americans' minds.

John Walker Lind, for example... maybe that guy wouldn't be blowing himself up; I dunno. But as "the American Taliban," he wouldn't exactly have been caught by the sort of profiling so many people are calling for. Nor would the Chechnyan women who blew themselves up in that Russian terror attack a few years ago.
