David Coppedge, a 14-year JPL veteran and team lead computer administrator on the Cassini Mission to Saturn, was demoted for lending ID-related DVDs to coworkers, behavior that one JPL complainant called 'harassment,' and another branded 'pushing religion.' After he filed suit to vindicate his free expression rights, JPL terminated Coppedge.
