If a person is on probation or parole, there’s a good chance he or she has waived the right to refuse being searched.
A fourth waiver is a condition of parole or probation that says an individual has given up his or her Fourth Amendment protections against unwarranted searches and seizures while under state or county supervision. Though the term “fourth waiver” refers to the actual agreement, it’s often personified to describe someone who’s under such an order.
Usually police must have reason to believe a person violated, or intends to violate, the law when making a stop. But if a police officer knows an individual is a fourth waiver, he or she has no obligation to prove reasonable suspicion before initiating a search. The officer can conduct a body, vehicle or home search without cause, so long as it doesn’t cross the line into harassment.
