Illegally gathered evidence can be admitted at trial if police officers have reason to believe they have a valid warrant or reason to search. Previously, police were responsible for “bad searches”. So far the new rule has been confined to errors made by judges or legislatures. Example: if a judge makes a mistake in issuing a warrant, the police officer is not responsible if she had good reason to believe that the warrant was valid.
