A federal appeals court on Wednesday said the authorities do not need probable-cause warrants to enable them to track a suspect’s every move via the GPS signals emitted from a suspect’s mobile phone. The decision, a big boost for the government’s surveillance powers, comes as prosecutors are shifting their focus to warrantless cell-tower locational tracking of suspects in the wake of a Supreme Court ruling in January that law enforcement should acquire probable-cause warrants from judges to affix GPS devices to vehicles and monitor their every move.
