AP U.S. Government and Politics 3.8: Amendments: Due Process and the Rights of the Accused

The Fifth Amendment restricts the national government from depriving a person of life, liberty, or property without due process of law. The Fourteenth Amendment imposes that obligation on states. Procedural due process concerns the methods government uses. Officials must follow nonarbitrary procedures rather than simply announce that a desired outcome justifies any method. A hearing and the opportunity to contest evidence can matter even when officials believe their policy serves the public.

The need for order does not erase liberty, and rights do not erase every governmental interest. Some restrictions can be justified, such as a restriction on speech presenting a danger to public safety under the relevant legal standard. That balance requires a reason tied to the particular right and circumstances. It does not permit officials to label every critic dangerous. In a criminal case, ask separately what procedure is required and whether evidence was obtained lawfully. A fair-sounding verdict cannot repair every earlier procedural violation.

The Miranda rule safeguards accused persons during custodial interrogation, meaning questioning while in police custody. Officers generally must advise the person of protections including the right to remain silent and the right to counsel before questioning. Arrest alone and custodial interrogation are different events. The warnings help make the privilege against compelled self-incrimination usable rather than merely words on paper.

The rule has a narrow public safety exception. In New York v. Quarles (1984), officers apprehended an armed suspect in a supermarket, found an empty holster, and asked where the gun was before giving warnings. The Court allowed the answer because an unsecured gun presented an immediate danger. This is a reason for the emergency question, not permission for every unwarned question in a criminal investigation. Quarles, majority opinion, pages 655-659. Distinguish questions needed to remove the danger from later questions aimed at proving a crime. A public safety justification is limited by the emergency that creates it.

In Gideon v. Wainwright (1963), Florida denied counsel to an indigent defendant charged with a felony. Gideon represented himself and was convicted. The unanimous Court reversed: the Sixth Amendment right to counsel is fundamental to a fair adversarial trial and applies to states through the Fourteenth Amendment. Lawyers are necessities in that system, so a state must provide counsel for an indigent felony defendant. Gideon, majority opinion, pages 339-345. Other protections include a speedy and public trial and an impartial jury.

The Fourth Amendment protects against unreasonable searches and seizures. Police generally need a warrant to search digital information on an arrested person's cell phone; possessing the phone does not itself authorize searching its data. Riley v. California (2014), opinion, pages 9-28. The exclusionary rule generally keeps evidence obtained in violation of the defendant's Fourth Amendment rights out of that person's criminal prosecution; recognized exceptions mean it is not an automatic remedy for every error. Congress also limited bulk telecommunication-metadata collection. The earlier PATRIOT Act Section 215 framework had been used for bulk telephone records; the USA FREEDOM Act of 2015 replaced that bulk program with a targeted system. These are historical statutory changes, not a claim that every authority remains in force today. That statutory example concerns collection limits, not a ban on all surveillance. USA FREEDOM Act, sections 101-103.
