(Philadelphia) -- A full U.S. appeals court in Philadelphia will decide whether police need a warrant to put a GPS tracking device on a suspect's car.
The case argued today involves a series of pharmacy robberies near Philadelphia, and pits the power of new technology against the right to privacy.
Courts so far have said police should have gotten a warrant before using a device that could track someone's every move for days or weeks.
The American Civil Liberties Union says the FBI agents should have been cautious because technology law was in flux at the time.
However, Assistant U.S. Attorney Bob Zauzmer says the tracking lasted only two days.
Electrician Harry Katzin and two brothers have pleaded not guilty to the 2010 robbery charges. They declined comment after the court arguments.
