Both papers emphasize the importance of thorough preparation. For example, the first paper advises, as one of the initial steps, preparation of a case workbook containing such items as a chronological diary of everything considered important by the prosecutor and ideas or insights that flash into the prosecutor's mind and are written down as soon as they occur. Careful organization of all material related to the case and a visit to the scene of the crime or any other relevant location are also recommended. Steps to follow in preparing the charge to the jury and preparing witnesses are also outlined. Both papers advise such actions as thorough examination of police reports, a rehearsal of examination and cross-examination of witnesses, and maintenance of notes on testimony offered by witnesses during the preliminary hearing. The first paper also recommends that a case be dismissed if after preparation, the prosecutor has strong doubt that the defendant is guilty. Case law examples are included.
