What is the primary purpose of the Exclusionary Rule?

The Exclusionary Rule exists to deter police from violating the Fourth Amendment by ensuring that evidence gathered through illegal searches or seizures cannot be used in court. This deterrent effect is the core purpose: if unlawfully obtained evidence can’t be admitted, officers have a strong incentive to follow constitutional protections. Today, the rule applies in both federal and state prosecutions (state applications come through the Fourteenth Amendment). It doesn’t mandate suppressing every piece of evidence at trial—only those obtained in violation of the Fourth Amendment—and it does not authorize admitting unlawfully obtained material. So the statement that it prohibits use of evidence obtained unlawfully in court best describes its purpose.
