Final answer:
The Exclusionary Rule is designed to keep evidence obtained from an unlawful or unconstitutional search or seizure out of a criminal trial.
Step-by-step explanation:
The Exclusionary Rule was designed to keep otherwise relevant evidence out of a criminal trial if its discovery results from an unlawful or unconstitutional search or seizure.
For example, if a police officer conducts a search without a warrant or without probable cause, any evidence found during that search may be excluded from the trial based on the Exclusionary Rule.
The primary goal of the Exclusionary Rule is to deter law enforcement from violating individuals' Fourth Amendment rights and to protect against unlawful search and seizure.
