ANSWER: The exclusionary rule states that any evidence that is obtain illegally, (i.e without a warrant) and any statements obtained through an illegal interrogation, which violate the Fourth, Fifth, or Sixth Amendment of the United States Constitution, will not be an acceptable evidence at a criminal trial in the court.
This exclutionary rule applies only to criminal case and not to civil case. Because John Bratton has a murder case charge, which are the dead bodies found in his properties. John Bratton's case is a civil case, and all evidence filed with his case should be admissible in the court of law.
Sara Sutton will not be charged for illegally selling gun, but will be charged for being a sole sponsor of a civil crime case charged against Bratton. This will make Sara Sutton to be prosecuted along side with Bratton, in the case.
If Sara Sutton is charged for illegally selling of guns, it will be a criminal case which will not be admissible by the court, due to exclusionary rule, because the police got their evidence without a search warrant.
John Bratton will not be charged for drug abuse offense, which is a criminal case, because all evidence provided will not be accepted due to exclusionary rule. Stankowitcz has busted into Bratton's apartment without a search warrant.
