John Yoo, in commenting on the Ghailani debacle, mentions something I had not known before:
In the middle of a hot war, though, releasing intelligence can be disastrous, because it informs the enemy of our knowledge, capabilities and intentions. That’s what happened when federal prosecutors tried the plotters of the 1993 World Trade Center bombing in civilian court. Al Qaeda learned which individuals the U.S. suspected of being in its organization, so it had an enormous intelligence advantage in planning future plots.
