What is the purpose of the exclusionary rule in relation to the Fourth Amendment?

The purpose of the exclusionary rule in relation to the Fourth Amendment is to deter police misconduct by excluding unlawfully obtained evidence. The Fourth Amendment protects individuals against unreasonable searches and seizures, and when law enforcement officers violate this constitutional protection, the exclusionary rule serves to prevent the government from benefiting from that violation by using the improperly obtained evidence in court.

This rule is grounded in the principle that allowing tainted evidence would undermine the integrity of the judicial system and encourage law enforcement to disregard constitutional rights. By excluding such evidence, the rule seeks to uphold the rule of law and ensure that police follow proper legal procedures, thereby promoting accountability and respect for citizens' rights.

In contrast, requiring all arrests to be performed with a warrant is not the function of the exclusionary rule but rather a requirement of the Fourth Amendment, which allows for certain exceptions. The assertion that all evidence obtained must be admissible overlooks the need for the evidence to be gathered lawfully. Lastly, simplifying the legal process for law enforcement does not align with the exclusionary rule's purpose; instead, it often complicates legal proceedings by necessitating hearings to determine the admissibility of evidence.
