Revise Your Expectations of Privacy Downward Accordingly

Via, if you have a cellphone, your location can be tracked by law enforcement, minus probable cause. Oh goody.
Since 2005, federal magistrate judges in at least 17 cases have denied federal requests for the less-precise cellphone tracking data absent a demonstration of probable cause that a crime is being committed. Some went out of their way to issue published opinions in these otherwise sealed cases.

"Permitting surreptitious conversion of a cellphone into a tracking device without probable cause raises serious Fourth Amendment concerns especially when the phone is in a house or other place where privacy is reasonably expected," said Judge Stephen William Smith of the Southern District of Texas, whose 2005 opinion on the matter was among the first published.

But judges in a majority of districts have ruled otherwise on this issue, Boyd said. Shortly after Smith issued his decision, a magistrate judge in the same district approved a federal request for cell-tower data without requiring probable cause. And in December 2005, Magistrate Judge Gabriel W. Gorenstein of the Southern District of New York, approving a request for cell-site data, wrote that because the government did not install the "tracking device" and the user chose to carry the phone and permit transmission of its information to a carrier, no warrant was needed.

And tracking us may get even easier in future:

The trend's secrecy is troubling, privacy advocates said. No government body tracks the number of cellphone location orders sought or obtained. Congressional oversight in this area is lacking, they said. And precise location data will be easier to get if the Federal Communication Commission adopts a Justice Department proposal to make the most detailed GPS data available automatically.

The fourth amendment is just so pre-Internet age.
