Anti-NSA effects already felt

From a fine Time Online column by Joe Klein (read the whole thing) comes the following on the early fallout from the NYT helping to keep our enemies informed as to how we fight terrorism:

At the very least, the Administration should have acted, with alacrity, to update the federal intelligence laws to include the powerful new technologies developed by the NSA.

But these concerns pale before the importance of the program. It would have been a scandal if the NSA had not been using these tools to track down the bad guys. There is evidence that the information harvested helped foil several plots and disrupt al-Qaeda operations.

There is also evidence, according to U.S. intelligence officials, that since the New York Times broke the story, the terrorists have modified their behavior, hampering our efforts to keep track of them—but also, on the plus side, hampering their ability to communicate with one another.

What would Al Qaeda do without the useful idiots at the Times?
