Writing for Wired, David Kravets takes note of a little-noticed surveillance-related case with wide implications for cell phone users. Following the lead of the Bush administration, the Obama administration is claiming that the Fourth Amendment protecting citizens against unreasonable searches and seizures, and against the issuing of warrants without probably cause, does not apply to the cell-site information mobile phone carriers keep about their customers. The Justice Department maintains that federal judges can be compelled to order mobile phone companies to release information that includes the closest cell-phone tower to which a user is connected at the beginning and end of a call. Companies generally keep this information for up to 18 months.
