Through the lens of Cicero's forensic oratory, Riggsby examines the four major public offenses: ambitus (bribery of the electorate), de sicariis et veneficiis (murder), vis (riot), and repetundae (extortion by provincial administrators). He persuasively argues that each of these offenses involves a violation of the proper relations between the state and the people, as interpreted by orators and juries. He concludes that in the late Roman Republic the only crimes were political crimes.
