The New Yorker points out the obvious implication if leaking to the press is taken as aiding the enemy:
Wikileaks “released” to the public, and in coöperation with other media outlets, not at some Al Qaeda dead drop. Readers of the New York Times, the Guardian, and other publications read it, too, after those outlets made the files not only available but more easily searchable. Perhaps another prosecutor, in this case or the next one, will argue that a defendant should have “understood the nature” of the Times. Or that of The New Yorker. What might it have meant, legally, if a copy of our magazine, bought at a news kiosk in Karachi, was found rolled up on the floor of bin Laden’s complex in Abbottabad? How much are we meant to be judged by what we can guess about the character of our readers?
