The Procedural Safeguards Governing the Exclusionary Rule in Criminal Trials
Quick fact
In the 1984 case United States v. Leon, the Supreme Court created the 'good-faith exception' to the exclusionary rule, allowing evidence to be admitted if police relied on a warrant that later turned out to be invalid—but only if the officers acted in objectively reasonable reliance on the judge's approval.
Why this is interesting
Imagine police knock on your door without a warrant, find illegal items, and arrest you—but what if the evidence was found in your neighbor's house? Can you challenge that evidence?
