A second federal judge has ruled that a suspect can be compelled to unlock their iPhone using their fingerprint in order to give investigators access to data which can be used as evidence against them. The first time this ever happened in a federal case was back in May, following a District Court ruling in 2014. The legal position of forcing suspects to use their fingerprints to unlock devices won't be known with certainty until a case reaches the U.S. Supreme Court, but lower court rulings so far appear to establish a precedent which is at odds with that concerning passcodes. Most constitutional experts appear to believe that the Fifth Amendment prevents a suspect from being compelled to reveal a password or passcode, as this would amount to forced self-incrimination -- though even this isn't certain. Fingerprints, in contrast, have traditionally been viewed as 'real or physical evidence,' meaning that police are entitled to take them without permission.
