What is the primary purpose of the exclusionary rule?

The primary purpose of the exclusionary rule is to deter police misconduct. This legal principle is grounded in the Fourth Amendment, which protects individuals from unreasonable searches and seizures. When law enforcement officials violate these rights, the exclusionary rule prevents the use of improperly obtained evidence in criminal trials. By making such evidence inadmissible, the rule aims to discourage officers from engaging in practices that infringe upon individuals' constitutional protections, thereby fostering accountability and adherence to lawful procedures. This deterrent effect is crucial for maintaining public trust in the justice system and ensuring that law enforcement operates within constitutional boundaries.
