Attorneys for convicted spy Jonathan Pollard labored for a decade and a half to win his freedom. But even as Pollard finally left prison on Friday, his lawyers announced that they aren’t satisfied with the terms of his release.

Pollard, an American former intelligence analyst, admitted nearly 30 years ago to illegally passing classified U.S. documents to Israel. Since 2000, he has been represented by Eliot Lauer and Jacques Semmelman of Curtis, Mallet-Prevost, Colt & Mosle, who secured parole for Pollard earlier this year.
