Once someone is arrested and booked on a criminal charge, that person may be held in jail for trial unless he furnishes a required bail amount. This amount is set by the magistrate, in accordance with the schedule of the offense and the risk involved, in order to ensure that the charged individual shows up to court to respond to the charges made against him/her. Bail may be posted with the court in several ways, usually in the form of cash, or by using a professional bondsman.
