¶ … Prosecution One of the harsh realities of the criminal justice system is the ability of defendants to defeat charges against them unless the prosecution has done its homework and prepared for the case properly. Irrespective of how thorough the criminal investigation may have been or how much evidence is available to support a criminal charge, cases can be lost at trial when prosecutors fail to properly prepare for its adjudication. In order to gain some fresh insights in this area, this paper provides a review of the relevant literature to describe the identify the evidentiary stages in the criminal justice process including the discovery process, applicable case law, the defense tactic of impeachment and general expectations for court and applicable rules to describe how officers can best prepare for trial. A summary of the research and important findings are presented in the conclusion.

Defense Tactic of Impeachment

One of the more common tactics used by defense attorneys is the impeachment of prosecution witnesses. According to Black's Law Dictionary (1991), the impeachment of a witness is "to call into question the veracity of a witness, by means of evidence adduced for such purpose, or the adducing of proof that a witness is unworthy of belief. (McWethy v. Lee, 272 N.E.2d 663, 668).
