Dick Morris writes (read his whole article here):

 After the National Security Administration picked up mentions of the "Brooklyn Bridge" in its warrantless wiretaps, it alerted New York City Police Commissioner Ray Kelly to the possibility of a terror attack against the bridge. Kelly flooded the bridge with cops and commissioned an engineering study to determine how one could bring down the bridge, plunging ten thousand people into the East River during rush hour.

The study said it was impossible to blow the bridge up – one would have been discovered – but that a terrorist could sever the cable holding it aloft with a torch. It would take weeks, but the terrorists could work, undetected, in a vacant building that housed the cables under the bridge. The traffic noises would mask their efforts, and the building was not patrolled or even visited by anyone.

The terrorist noted the cops on the bridge and sent a message, intercepted by the NSA, that it was "too hot on the Brooklyn Bridge." But it was not until we waterboarded Khalid Sheik Mohammed that we learned the identity of the al-Qaida operative – Lyman Farris. On learning his name, the New York Police raided his Brooklyn apartment. Chillingly, they found the equipment he would need to bring down the bridge and an engineering diagram (akin to that which Kelly had ordered) identifying where they would have to stand to cut the cables.

 Does Obama really want to prosecute the anti-terror investigators who saved thousands by waterboarding Mohammed and learning this information?

Yes, he does. The Democrats want to, because punishing the last administration is (obviously) far more important to them than national security. The true name for their affected moral objection to ‘torturing’ terrorists, is spite.
