There's no doubt that Al Qaeda's Khalid Sheikh Mohammed is a dangerous terrorist. But the Pentagon's recently-released Khalid-confessions (including taking credit for the murder of journalist Daniel Pearl) should be greeted with a little more critical thinking by the mainstream news media (now distracted from covering Alberto Gonzales, Karl Rove and the U.S. attorney firing scandal).
In the 1980s, serial killer Henry Lee Lucas confessed to a plethora of murders, including that of Adam Walsh. Most of these murders, including young Adam's, weren't committed by Lucas and his companion in crime Ottis Toole. But these confessions made for sensational reading--and at the time it was alleged that Texas authorities didn't look too closely at Lucas' bravado and falsehood because cold cases had a better chance of closure.
It remains to be seen just how many crimes against humanity that Khalid Sheikh Mohammed actually committed. Let's not blindly accept everything he says at face value.
