As in most of California, some misdemeanor crimes are prosecuted by local city attorneys. City attorneys prosecute misdemeanors and infractions that are violations of the municipal code governing the incorporated city's jurisdiction. All other misdemeanor, felony, and infraction violations that occur within San Diego County are prosecuted by the district attorney.
The District Attorney's office claims a 94.1 percent conviction rate. The conviction rate for driving under the influence (DUI) in 2010 was 98% of 11,000 people charged with felony or misdemeanor DUI.
