Botched court doc outs Google as respondent in national security flap
An error by the US Department of Justice's document-redaction staff has inadvertently let slip a secret that the DoJ has spent months battling in the courts to protect – albeit one that will come as a surprise to no one.

The letters are so secretive, in fact, that companies that receive them aren't allowed to discuss them or even admit that they exist.
