Assuming you're talking about the US justice system . . . individuals still have rights when they are accused of criminal acts because our justice system requires that each individual be innocent until proven guilty in a court of law. Until such point that they are proven guilty, they are assumed innocent, and are entitled to the same rights as you or I am, having not committed any criminal acts. . . . THEY HAVE TO BE PROVEN GUILTY FIRST BEFORE THEY LOSE ANY RIGHTS AS A CITIZEN
