Explanation: The 4th Amendment protects people from unreasonable searches and seizures without probable cause. Meaning, unless there is a warrant that specifically states who/what is being searched, the Government, or anyone, is not constitutionally allowed to search you. Therefore, the FBI can not examine someone's phone without consent or a search warrant.
Two roles of magistrate judges are : ( B ) to isuue court orders ( in pre-trial matters ) ; and ( D ) to hear preliminary evidence and decide if a case should be brought to trial. Magistrate judges are appointed by vote of federal district judges for terms of eight years; they can be reelected.
