This landmark case extended the protections of the Bill of Rights to the states, reinforcing the principle that individuals have rights against government actions. Mapp v. Ohio empowered citizens by ensuring that their constitutional rights are upheld in legal proceedings, thereby maintaining the integrity of the judicial system. The exclusionary rule is crucial for safeguarding individual freedoms and advocating for responsible law enforcement practices.
