As part of the effort, NEWSWEEK has learned, Mueller’s top aides have directed chiefs of the bureau’s 56 field offices to develop “demographic� profiles of their localities—including tallying the number of mosques. Those profiles are then being used, along with other factors, to set specific numerical goals for counter terrorism investigations and secret national-security wiretaps in each region. Top bureau officials have signaled that if field offices don’t meet their pre-established goals, they may be subjected to special reviews by inspection teams from headquarters.
