What is the primary purpose of the exclusionary rule?

The primary purpose of the exclusionary rule is to deter law enforcement from obtaining evidence illegally. This legal principle is designed to protect the Fourth Amendment rights of individuals, ensuring that evidence obtained through violations of constitutional protections—such as unreasonable searches and seizures—cannot be used in court. By enforcing this rule, the judicial system aims to discourage police practices that disregard constitutional rights, thereby upholding the integrity of the legal process.

When law enforcement is aware that illegally obtained evidence will be excluded from judicial proceedings, it serves as a strong incentive for them to adhere to legal standards and procedures during investigations. This contributes to a more just legal system and reinforces the importance of lawful conduct in policing.
