Darren Drahota was convicted of disturbing the peace and fined $250 for e-mails he sent in 2006 to former University of Nebraska-Lincoln political science professor
Bill Avery. At the time, Avery was running for a seat in the Nebraska Legislature, which he won, and Drahota was a UNL student. A California law professor who took Drahota's case to the state Supreme Court,
Eugene Volokh, had argued that although Drahota's messages irritated Avery, their contents alone didn't merit a criminal accusation.
