Fluffeh writes "CTIA (The mobile operators' industry association) is opposing a California law proposing that a court order be required prior to disclosing personal information. The law seems to be in opposition to the federal government's attempts to wash away the last requirements to get at any information about citizens, but CTIA claims (PDF) '... the wireless industry opposes SB 1434 as it could create greater confusion for wireless providers when responding to legitimate law enforcement requests.' The EFF and the ACLU have been arguing strongly for the bill which is to be voted on shortly." A charming quote from CTIA: "For example, the definition of 'location information' is so sweeping that it could implicate information generally considered basic subscriber information under federal law. Since the implications of this definition are unclear, wireless providers will have difficulty figuring out how to respond to requests for such information. It could place providers in the position of requiring warrants for all law enforcement requests."
