What is the main effect of the exclusionary rule?

• A. It deters unconstitutional police conduct by excluding unlawfully obtained evidence at trial.
• B. It ensures all collected evidence is admitted.
• C. It allows use of illegally obtained statements if voluntariness is claimed.
• D. It only applies to state courts.

Answer: (A)

Deterring unconstitutional police conduct by excluding unlawfully obtained evidence at trial is the main effect. When a search or seizure violates the Fourth Amendment, the evidence uncovered is typically barred from use in court, which motivates law enforcement to follow proper procedures. It isn’t about guaranteeing that every piece of evidence is admitted, and illegally obtained statements aren’t automatically admissible just because voluntariness is claimed, except under specific exceptions. The rule applies to both federal and state courts.
