Newsweek reports on the Buffalo Six investigation in The Hunt for Sleeper Cells.

"Not surprisingly, civil libertarians are troubled by the Buffalo case, and worry it could erode a basic constitutional right: freedom of association. But the courtroom drama playing out in Buffalo may be just a hint of things to come. "

"Justice Department officials fear that dozens of sleeper cells, with hundreds of members, may be quietly plotting the next attack from within our borders, and Attorney General John Ashcroft has vowed to root them out even if that means stretching the limits of the law. 'We don't have the luxury to take chances,' a source close to Ashcroft told NEWSWEEK. 'If we could have locked up Mohamed Atta before 9-11, do you think people would criticize us? We're going to do whatever we have to do to hold them until we find out who they really are'".
