They are public prosecutors.
Generally, there are district attorney's offices and criminal divisions of the state attorney's general offices at the state level. These offices are organized by county. The District Attorney for the county is usually an elected official. Depending upon the size of the District Attorney's office, it may have multiple units that focus upon different types of crimes, such as domestic violence or homicides. If you work with a smaller District Attorney's office, you may have the option of handling diverse caseloads.
One of the largest advantages of working for a District Attorney's office is that you can get immediate and meaningful trial experience. This is something that many attorneys who work in law firms must wait for years to get. As an Assistant District Attorney, you will generally start out doing smaller misdemeanor cases and then work your way up to more significant work. On the higher end, District Attorneys have a great deal of discretion in how cases are investigated and prosecuted. The entire process of working as a District Attorney can result in a tremendously fulfilling career for people who want meaningful trial and court experience.
