Whether or not former Israeli spy Jonathan Pollard is still a man who knows too much cannot be considered in his effort to loosen the terms of his parole, a federal appellate judge said.

Pollard served 28 years in prison for a conspiracy to deliver national defense information to a foreign government. Following his release, he challenged restrictions imposed by the U.S. Parole Commission that he wear a GPS tracking device and that his probation officer can search his computer without warning. Last year, Southern District Judge Katherine Forrest upheld the commission’s ruling.
