In a 5-4 decision on Friday the justices said that police need warrants to gather phone location data as evidence for trials. That reversed and remanded a decision by the Sixth Circuit Court of Appeals.
Carpenter v. United States is thehas ruled on. That makes it a landmark decision regarding how law enforcement agencies can use technology as they build cases. The court heard arguments in the case on Nov. 29.
The dispute dates back to a 2011 robbery in Detroit, after which police gathered months of phone location data from Timothy Carpenter’s phone provider. They pulled together 12,898 different locations from Carpenter, over 127 days.
