The Obama administration’s Justice Department is arguing that American citizens have no right to keep their locations private. Law enforcement, it argues, is perfectly correct in seeking detailed locational histories of private cellphone locations, without any need for a warrant.
The Obama administration will tell federal judges in New Orleans today that warrantless tracking of the location of Americans’ mobile devices is perfectly legal.
Federal prosecutors are planning to argue that they should be able to obtain stored records revealing the minute-by-minute movements of mobile users over a 60-day period — in this case, T-Mobile and MetroPCS customers — without having to ask a judge to approve a warrant first.
The case highlights how valuable location data is for police, especially when it’s tied to devices that millions of people carry with them almost all the time. Records kept by wireless carriers can hint at or reveal medical treatments, political associations, religious convictions, and even whether someone is cheating on his or her spouse.
Cellphone location data is sufficient to track a person’s location and activities in extreme detail and certainly it is unreasonable to assume that citizens has no expectation that law enforcement can “follow them” without the minimum requirement of a warrant. Outrageous.
Update: Now this…
California Gov. Jerry Brown has vetoed legislation that would have required the state’s authorities to get a probable-cause warrant signed by a judge to obtain location information from electronic devices such as tablets, mobile phones and laptops.
