Location Data: The More They Know

The Supreme Court will hear oral arguments in Carpenter v. United States on November 29th. Carpenter centers on whether law enforcement needs a warrant to access 127 days of historic cell-site location information (CSLI). The case is important because of the great quantity of demands for location information now being made by law enforcement, because the location information that is sought is very revealing, and because law enforcement often obtains such data without obtaining a warrant, which increases the likelihood that sensitive location information about innocent people is collected.

In fact, it authorizes surveillance of people engaged in harmless activity.

DHS’s Misguided Social Media Retention Policy Jeopardizes Fundamental Freedoms

Last month, the Department of Homeland Security (DHS) issued an alarming notice that DHS would now retain social media information in Alien-Files (A-Files). A-Files are government records, generated in the immigration context, that include the records of an individual as they pass through the United States immigration process, and are retained by DHS for 100 years after the individual’s birthdate. This retention of social media information should not be brushed off as ‘business as usual’ for DHS. This policy, and its negative consequences for the free expression and privacy rights of both immigrants and U.S. citizens.
