Wow: 'The fact that federal, state, and local law enforcement can obtain communications "metadata"—URLs of sites visited, e-mail message headers, numbers dialed, GPS locations, etc.—without any
real oversight or reporting requirements should be shocking, but it isn't. The courts ruled in 2005 that law enforcement doesn't need to show probable cause to obtain your physical location
via the cell phone grid. All of the aforementioned metadata can be accessed with an easy-to-obtain pen register/trap & trace order. But given the volume of requests, it's hard to imagine that
the courts are involved in all of these.'
