Instead of serving a prison sentence, a defendant may be required to serve probation. During probation, sometimes known as a suspended sentence, the defendant may be required to comply with conditions of release. The defendant's probation is supervised by a probation officer whose job it is to set up regularly meetings with the defendant.
Individuals on probation may be prohibited from carrying a weapon, leaving the jurisdiction or working around minors. Generally, an individual must give up certain rights -- such as the the protections against unreasonable searches and seizures -- in order to be released on probation.
Searches must be reasonable 
If the defendant fails to comply with terms of probation the probation officer may request the sentencing court hold a revocation hearing. If the court determines that the individual violated their probation, they may revoke the probation and re-instate the prison sentence.
