07 Rights of the Accused and Personal Privacy

Constitutional Framework

The Constitution permits government to investigate and punish crime, but it limits the methods government may use. These limits protect privacy, prevent coercion, and ensure fair criminal proceedings.

The principal constitutional sources are:

• The Fourth Amendment, which regulates searches and seizures.

• The Fifth Amendment, which protects against compelled self-incrimination, double jeopardy, and deprivation of life, liberty, or property without due process.

• The Sixth Amendment, which protects trial rights such as a speedy and public trial, an impartial jury, notice of the accusation, confrontation of witnesses, compulsory process, and assistance of counsel.

• The Fourteenth Amendment, which requires due process and applies many criminal-procedure protections to state governments through incorporation.

The Fifth Amendment generally limits the federal government, while the Fourteenth Amendment applies similar protections to the states. Together, these provisions create a framework in which effective law enforcement must be balanced against individual liberty and privacy.

Takeaway: Criminal-procedure rights regulate both how government gathers information and how it prosecutes an accused person.

Searches, Seizures, and Personal Privacy

The Fourth Amendment protects people, houses, papers, and effects from unreasonable searches and seizures. A search may occur when government intrudes on a constitutionally protected privacy or property interest. A seizure may occur when government meaningfully interferes with a person's possession of property or restrains freedom of movement.

A warrant is ordinarily based on probable cause, supported by oath or affirmation, and particularized as to the place, persons, or things involved. However, the central question is whether government action was reasonable under the circumstances. Courts recognize exceptions involving consent, a search incident to a lawful arrest, exigent circumstances, automobiles, plain view, and certain border searches.

Privacy beyond physical places

In Katz v. United States, federal agents recorded telephone conversations from outside a public telephone booth. The Supreme Court rejected the idea that no search occurred merely because officers did not enter the booth. The Fourth Amendment protects people, and the caller had a reasonable expectation of privacy in the conversation.

This principle means that electronic surveillance can be a search even without physical entry. For example, secretly placing a microphone outside a home to capture private conversations is not automatically constitutional merely because officers remain outside.

Stops and frisks

Terry v. Ohio distinguished a brief investigative stop from a full arrest. A stop requires reasonable suspicion, meaning specific and articulable facts suggesting that criminal activity is occurring, has occurred, or is about to occur. A frisk is a limited pat-down for weapons and requires a reasonable belief that the person is armed and dangerous.

The standards differ:

• Reasonable suspicion can justify a limited stop.

• Probable cause is a stronger basis and is generally required for an arrest or warrant.

• A frisk is not a general search for evidence; its purpose is officer safety.

Digital privacy

Modern technology can reveal extensive information about a person's life. Riley v. California held that police generally need a warrant to search the digital contents of a cell phone seized from an arrested person. Although the phone can contain communications, location information, associations, photographs, and private documents, it is not treated like an ordinary physical container.

Carpenter v. United States held that obtaining historical cell-site location information from a wireless provider is generally a Fourth Amendment search requiring a warrant. The decision recognized that records held by a company may still reveal a comprehensive and deeply private record of a person's movements.

Takeaway: Fourth Amendment analysis focuses on reasonableness, privacy, and the scope of government conduct. The protection applies to physical searches, investigative stops, electronic surveillance, cell phones, and location records.

The Exclusionary Rule

The exclusionary rule generally prevents the government from using evidence obtained through an unconstitutional search or seizure in its criminal case. In Mapp v. Ohio, the Supreme Court applied this rule to the states through the Fourteenth Amendment.

The rule primarily serves as a judicial remedy intended to deter unconstitutional police conduct. It does not automatically require dismissal of every case in which a violation occurred. Instead, it commonly prevents particular evidence from being introduced against the defendant.

The rule has limits. In United States v. Leon, the Court recognized a good-faith exception for evidence obtained by officers who reasonably relied on a search warrant later found to be defective. Excluding reliable evidence may provide little additional deterrence when officers acted reasonably and relied on a neutral magistrate's warrant.

A complete analysis therefore asks two questions:

1. Was the evidence obtained through unconstitutional government conduct?

2. If so, does an exception limit the exclusionary remedy?

Takeaway: The exclusionary rule addresses the use of unlawfully obtained evidence, but its application depends on the violation, the purpose of the remedy, and recognized exceptions.

Due Process and Incorporation

Due process of law requires fundamentally fair procedures before government deprives a person of life, liberty, or property. Procedural due process concerns the methods government must use, including notice, a neutral decision maker, and an opportunity to be heard. Substantive due process concerns whether government may infringe certain fundamental liberties even when it follows proper procedures.

In criminal cases, due process supports:

• notice of the charges;

• a fair and impartial tribunal;

• protection against fundamentally unreliable procedures;

• disclosure of constitutionally required evidence;

• a meaningful opportunity to present a defense; and

• proof of guilt beyond a reasonable doubt.

The Due Process Clause also supplies the constitutional basis for incorporation, through which many Bill of Rights protections apply to state governments. As a result, defendants in state court generally receive many of the same fundamental protections as defendants in federal court.

Takeaway: Due process is concerned with the fundamental fairness of criminal procedures and helps make constitutional protections effective against both federal and state governments.

Self-Incrimination and Miranda Safeguards

The Fifth Amendment privilege protects a person from being compelled in a criminal case to be a witness against himself or herself. It protects compelled testimonial communication, but it does not generally prevent the government from collecting physical evidence such as fingerprints, photographs, or blood samples through constitutionally valid procedures.

The privilege serves several related purposes:

• preventing coercive efforts to force confessions;

• preserving the presumption of innocence;

• placing the burden of proving guilt on the prosecution; and

• protecting the dignity and autonomy of the accused.

Miranda safeguards

Miranda v. Arizona requires procedural safeguards before custodial interrogation. Police generally must inform a person in custody that the person may remain silent, that statements may be used in court, that the person may consult an attorney, and that an attorney will be appointed if the person cannot afford one.

A waiver is valid only when it is knowing, intelligent, and voluntary. Custody means a formal arrest or restraint comparable to arrest. Interrogation means questioning or its functional equivalent that is reasonably likely to elicit an incriminating response. A voluntary conversation with an officer at a person's home may not be custodial interrogation, while questioning an arrested suspect in an interrogation room ordinarily is.

Miranda does not prohibit all questioning. It protects the suspect's ability to make a voluntary choice about speaking.

Invoking counsel

Under Edwards v. Arizona, when a suspect clearly invokes the right to counsel during custodial interrogation, police generally may not continue questioning until counsel is available, unless the suspect reinitiates communication.

This Miranda-based protection differs from the Sixth Amendment right to counsel. The Miranda rule is primarily connected to the Fifth Amendment privilege and custodial interrogation. The Sixth Amendment right is tied to a particular criminal case and generally attaches after formal proceedings begin.

Takeaway: The Fifth Amendment regulates compelled testimonial communication, while Miranda adds procedural safeguards that protect voluntary decision-making during custodial interrogation.

Counsel and Sixth Amendment Trial Rights

The Sixth Amendment guarantees assistance of counsel in criminal prosecutions. In Gideon v. Wainwright, the Supreme Court held that indigent defendants charged with serious offenses have a constitutional right to appointed counsel in state criminal trials. The guarantee was applied to the states through the Fourteenth Amendment.

Counsel is important because criminal proceedings involve rules of evidence, jury selection, cross-examination, motions, constitutional objections, and sentencing consequences. The Sixth Amendment also protects effective assistance of counsel. Serious attorney errors may justify a remedy when they prejudice the defense.

The Sixth Amendment's other trial guarantees include:

• Speedy trial: limits unjustified government delay.

• Public trial: promotes transparency and discourages secret proceedings.

• Impartial jury: requires a fair fact-finding body.

• Notice of accusation: gives the accused an opportunity to prepare a defense.

• Confrontation: generally permits cross-examination of witnesses who testify against the accused.

• Compulsory process: permits the defense to obtain witnesses and evidence.

• Assistance of counsel: provides legal representation at critical stages.

These rights support the adversary system, in which the prosecution and defense present competing evidence before a neutral judge and jury.

Takeaway: The Sixth Amendment protects meaningful participation in the criminal process, especially through counsel and a fair trial.

Applying the Protections to a Criminal Investigation

Constitutional protections operate at different stages of a criminal investigation and prosecution. Consider the following sequence:

1. Police receive an unverified tip that a person possesses illegal drugs.

2. An officer observes the person repeatedly entering and leaving a store but sees no crime.

3. The officer stops the person and conducts a pat-down.

4. Police arrest the person and seize a cell phone.

5. At the station, officers question the person without warnings.

6. The person cannot afford a lawyer and is brought to trial without appointed counsel.

The analysis proceeds step by step:

• An unverified tip alone may not establish probable cause.

• The stop requires reasonable suspicion based on specific facts; innocent conduct alone may be insufficient.

• The frisk must be supported by a reasonable belief that the person is armed and dangerous.

• The cell phone may be seized incident to arrest, but its digital contents generally require a warrant under Riley v. California.

• Custodial interrogation ordinarily requires Miranda warnings.

• A clear request for counsel can restrict further questioning under Edwards v. Arizona.

• An indigent defendant facing a serious criminal charge generally has a right to appointed counsel under Gideon v. Wainwright.

• Evidence obtained through an unconstitutional search may be suppressed under Mapp v. Ohio, although exceptions such as good-faith reliance may apply.

The protections can be compared by the question each one asks:

• Fourth Amendment: Was the search or seizure reasonable?

• Exclusionary rule: Should unlawfully obtained evidence be suppressed?

• Fifth Amendment privilege: Was the person compelled to provide incriminating testimony?

• Sixth Amendment counsel: Was the accused denied legal assistance at a critical stage?

• Fourteenth Amendment due process: Were the procedures fundamentally fair?

Final takeaway: The Fourth Amendment regulates evidence gathering, the Fifth Amendment regulates compelled statements, the Sixth Amendment protects the accused after criminal proceedings begin, and the Fourteenth Amendment applies fundamental protections to state governments. Together, these rules balance effective law enforcement with privacy, fairness, and individual liberty.
