The Sixth Circuit U.S. Court of Appeals has ruled that law enforcement officers don't need a warrant to track the location of a subject via the GPS data from a cell phone.
The Tuesday ruling came in the case United States v. Skinner in which Melvin Skinner was tracked between Arizona and Tennessee by Drug Enforcement Administration agents. Skinner and his son were arrested at a rest stop near Abilene, Texas, with a motor home filled with over 1,100 pounds of marijuana.
