Amen. I'm glad that someone with public visibility, like Charles, is asking these questions.
The New York Times, which is one of the newspapers publishing these documents, has redacted some of them, both on the grounds of protecting private citizens named in the documents whose lives might be threatened, and on the grounds of protecting American intelligence efforts.
The Times has withheld from articles and removed from documents it is posting online the names of some people who spoke privately to diplomats and might be at risk if they were publicly identified. The Times is also withholding some passages or entire cables whose disclosure could compromise American intelligence efforts.
