Many on the left are defending the New York TImes by saying that the paper revealed nothing that can be considered deterimental to our government's ability to execute it effectively.

Unfortunately for them, the chairman of the 9/11 commission (among others) disagrees:

Thomas Kean, the co-chairman of the September 11 Commission, was briefed several weeks ago about the Treasury Department’s terrorist-finance program, and after the session, Kean says, “I came away with the idea that this was a good program, one that was legal, one that was not violating anybody’s civil liberties…and something the U.S. government should be doing to make us safer.”

Kean tells National Review Online that the New York Times’s decision to expose the terrorist finance effort — Kean called Times executive editor Bill Keller in an attempt to persuade him not to publish — has done terrible damage to the program. “I think it’s over,” Kean says. “Terrorists read the newspapers. Once the program became known, then obviously the terrorists were not going to use these methods any more.”
