Probation is a time of supervision over a wrongdoer, set by the court as opposed to serving time in jail. A guilty party on probation is required to take after specific conditions put forward by the court, frequently under the supervision of a probation supervisor. Amid the time of probation a wrongdoer faces the danger of being imprisoned if discovered breaking the tenets set by the court or probation supervisor.
