Compare and contrast the roles of the professional and nonprofessional courtroom

The courtroom work group is guided by statutory requirements
and ethical considerations, and its members are generally dedicated to bringing the criminal trial and other courtroom procedures to a successful close. This chapter describes the role that each professional participant plays in the courtroom. The judge, for example, has the primary duty of
ensuring a fair trial—in short, seeing that justice prevails.  Nonprofessional courtroom participants include lay witnesses, jurors, the victim, the defendant, and spectators and
members of the press. Non judicial courtroom personnel, or outsiders, may be unwilling or inadvertent participants in a criminal trial, but they fill a necessary role to make the system work.  Defendants, victims, jurors, and most witnesses are usually unwilling or inadvertent participants in criminal trials. Although they are outsiders who lack the status of paid professional participants, these are precisely the people who provide the grist for the judicial mill. The press, a willing player in many criminal trials, makes up another group of outsiders.
