Which amendment is the Exclusionary Rule grounded in?

The Exclusionary Rule is grounded in the 4th Amendment, which protects individuals from unreasonable searches and seizures. This legal principle establishes that evidence obtained in violation of a person's constitutional rights cannot be used against them in a court of law. The rule is intended to deter law enforcement from conducting illegal searches and to uphold the integrity of the judicial process. The 4th Amendment's focus on the security and privacy of individuals directly correlates with the rationale behind the Exclusionary Rule, as it emphasizes the need for law enforcement to adhere to constitutional standards when gathering evidence.
