What does the "exclusionary rule" state?

The exclusionary rule is a fundamental legal principle that prohibits the use of evidence obtained in violation of a person’s constitutional rights, particularly those protected by the Fourth Amendment, which guards against unreasonable searches and seizures. This rule is intended to deter law enforcement from conducting illegal searches and collecting evidence unlawfully. When evidence is obtained through such violations, it is deemed inadmissible in court, thereby reinforcing the integrity of the judicial process and protecting individual rights.

The option stating that all evidence must be collected with a warrant does not fully capture the nuance of the exclusionary rule, as there are certain exceptions where evidence collected without a warrant might still be admissible, such as in cases of exigent circumstances or consent. The option regarding the timeframe for presenting evidence touches on procedural aspects but is not related to the principles established by the exclusionary rule. The requirement that all confessions must be recorded is a policy aimed at ensuring transparency and protecting against coercion but is not directly connected to the exclusionary rule itself. Therefore, the correct answer encapsulates the core idea that evidence obtained in violation of constitutional protections cannot be used in judicial proceedings, which is essential for upholding justice and individual rights.
