An anonymous reader writes "In a time when the government avows that it cannot carry out justice without issuing secret warrants and National Security Letters to anyone other than the suspect, it is truly noteworthy when news breaks that the FBI, facing push-back from the likes of a company such as Microsoft, finds that it can indeed gather the information it needs for its investigation through a regular search warrant applied directly to its suspect. Such was the case on Thursday. Court documents (PDF) reveal that Microsoft filed a petition against the National Security Letter (NSL) it received involving one of its customers, citing violations to the First Amendment. The FBI later withdrew the NSL and went after their suspect in the old, Constitutionally-sound way. A federal judge ruled last year that the NSLs impinge on free speech' That judgement has been stayed, of course, pending appeal."
