It would surprise me if the police hadn't gone to OnStar to get exactly that kind of tracking information. Even if they haven't, just reframing the case the way you have reduces the applicability of the ruling significantly. It wouldn't be hard to argue "the Internet is a public place" and as such, there is no expectation of privacy (perhaps with the exception of SSL, but AFAIK, PCIPA doesn't require keeping the actual data, just the logs of where you went, which, even with SSL, the IP address you are visiting is clear text).

I think we will need new legislation or some serious divine intervention for this decision to protect our online privacy from the government.
