New York Times editor Bill Keller's comments about the range of leaked documents by WikiLeaks fell into three categories: First was the importance of protecting individuals who had spoken candidly to American diplomats in oppressive countries. We almost always agreed on those and were grateful to the government for pointing out some we overlooked: That sometimes meant not just removing the name, but also references to institutions that might give a clue to an identity and sometimes even the dates of conversations, which might be compared with surveillance tapes of an American Embassy to reveal who was visiting the diplomats that day. The second category included sensitive American programs, usually related to intelligence. We agreed to withhold some of this information, like a cable describing an intelligence-sharing program that took years to arrange and might be lost if exposed. In other cases, we went away convinced that publication would cause some embarrassment, but no real harm. The third category consisted of cables that disclosed candid comments by and about foreign officials, including heads of state. The State Department feared publication would strain relations with those countries. We were mostly unconvinced!
