From the Atlanta Monthly in October 2003:

It is likely that some captured terrorists' names and arrests have not yet been revealed; people may be held for months before their "arrests" are staged. Once a top-level suspect is publicly known to be in custody, his intelligence value falls. His organization scatters, altering its plans, disguises, cover stories, codes, tactics, and communication methods. The maximum opportunity for intelligence gathering comes in the first hours after an arrest, before others in a group can possibly know that their walls have been breached. Keeping an arrest quiet for days or weeks prolongs this opportunity. If March 1 was in fact the day of Sheikh Mohammed's capture, then the cameras and the headlines were an important intelligence failure. The arrest of the senior al-Qaeda figure Abu Anas Liby, in Sudan in February of 2002, was not made public until a month later, when U.S. efforts to have him transferred to custody in Egypt were leaked to the Sunday Times of London.
