WITHOUT A COURT ORDER, Google gives up IP of anonymous blogger.

UPDATE: Compare Amazon.

ANOTHER UPDATE: More on the Amazon case from Orin Kerr: “Seems kinda weird to me: can bad reporting by the press make perfectly lawful investigations unlawful?”

MORE: Further thoughts here: “In terms of the law, here’s what I don’t get, or rather, here’s one of the several things I don’t get: If public misunderstanding of Judge Crocker’s decision makes the otherwise constitutional subpoena unconstitutional, can’t Judge Crocker write his opinion in a calming and soothing way to make the subpoena constitutional? Or are bloggers and their fiery rhetoric really that incorrigible?”
