In the Case of United States V

In the case of United States v. Leon, a police officer executed a facially valid search warrant, which was later determined to be defective because of insufficient probable cause. The United States Supreme Court, on review:

A) determined that, because the search warrant was invalid, the exclusionary rule would apply, and the evidence should not have been admitted.
B) recognized a good-faith exception to the exclusionary rule, in a situation where a defective warrant has been issued by a judge and the officer has no reason to believe that the warrant is defective.
C) recognized that suppressing evidence when the officer acts in good faith does not achieve the purposes of the exclusionary rule and indicated that the exclusionary rule would no longer be applied in search and seizure situations.
D) held that a search warrant, valid on its face, may be legally executed by a police officer even though the officer is aware that the warrant is based on insufficient probable cause.
