Court: Warrantless requests to track cellphones, Internet use grew sevenfold in D.C. in three years

Sealed law enforcement requests to track Americans without a warrant through cellphone location records or Internet activity grew sevenfold in the past three years in the District, new information released by a federal judge shows. Details about the growth come as the US Supreme Court weighs whether to rein in such rapidly expanding demands. Legal experts said the disclosure appears to mark a first, and that neither the Justice Department nor private companies have previously made public such specific data about how often law enforcement agencies seek those court orders. The summary data gave counts of requests by year from 2008 through 2016 made in criminal cases handled by the Justice Department or US attorney’s office for the District. Details about each individual case, such as the name of a suspect or what records were sought, were not disclosed.

The requests were made under a 1986 statute that enables law enforcement agencies to obtain court orders requiring ­communication service providers to turn over records about individual customers. The orders do not apply to information about telephone calls, such as the time, date, duration and numbers dialed, which can be obtained in other ways. Instead, the requests seek individuals’ Internet connection records or cellphone tower records. Those records exclude the content of communications but can be highly valuable to investigators seeking to establish a history or pattern of movement, conduct or relationships. The information requests can include Internet browsing logs and activity; the time, date, size, sender and recipient of email, instant or social media messages, or other transaction records; as well as computer identification numbers and information about websites that a user accessed.
