As many others are noting, it seems concerning that the New York Times (in particular) takes such liberty to report on classified activities. They seem to justify it by the degree of public interest they thus garner. Nevertheless, national security and success in the prevention of future terrorists attacks are of greater, long-term, public interest. The degree to which national security is jeopardized by this reporting is perhaps difficult to estimate, but it is surely deemed to be real by those in the know (otherwise the material would not be classified).
Hugh Hewitt has a good post, including a letter to the NYT by Sergeant T.F. Boggs, on this topic. Given the recent sting operation in Miami, this issue has particular relevance. Those in office ought to take this matter seriously.
