A look at legislative and judicial policy suggests that various professionals assist the criminal justice system in carrying out these tasks, among which the most important are legal doctors. The legal practitioners, through the criminal process, fulfill a fair trial and, while removing the ambiguity of the specialized issues at the trial stage, also facilitate the execution of the penalties.
