What is the exclusionary rule designed to do?

The exclusionary rule is a crucial principle in criminal law that aims to protect individuals' Fourth Amendment rights against unreasonable searches and seizures. It specifically serves to suppress evidence that has been obtained in violation of these rights, such as through illegal searches or coerced confessions. The fundamental purpose of the exclusionary rule is to deter law enforcement from conducting illegal searches and to uphold the integrity of the judicial system by ensuring that no illegally obtained evidence is used in court proceedings. This helps to maintain public confidence in the fairness and impartiality of the justice system. As a result, when evidence is derived from such illegal methods, it is considered inadmissible in court, reinforcing the idea that constitutional rights must be respected.
