The Fourth Amendment limits law enforcement by requiring evidence to be collected with a warrant. What is this called?

The correct answer is C. The exclusionary rule.

The exclusionary rule is a legal principle that prohibits the use of evidence collected in violation of a person’s Fourth Amendment rights. This means that if law enforcement obtains evidence without a proper warrant or probable cause, that evidence cannot be used in court. The rule is designed to deter police misconduct and protect individuals’ rights against unreasonable searches and seizures.
