How Miranda Rights Work

"You have the right to remain silent."

So begins one of the most iconic recitations in U.S. culture, and TV crime show fans around the world know what comes next: "Anything you say can and will be used against you in a court of law. You have the right to an attorney. If you cannot afford an attorney, one will be provided for you. Do you understand the rights I have just read to you? With these rights in mind, do you wish to speak to me?"

The so-called Miranda rights are a cornerstone of the U.S. justice system. They're said so often in TV and movies they've nearly lost all meaning, at least to those outside the criminal, legal and law-enforcement communities. But in April 2013, followers of the Boston Marathon bombings case were reminded that they do, in fact, mean a lot.

After an epic manhunt put much of Boston on lockdown, the sole surviving suspect in the bombings was captured. Dzhokhar Tsarnaev was in custody, and he'd confessed. The city breathed a sigh of relief. Within hours, though, the headlines announced what appeared to be a hitch: Tsarnaev, it seemed, hadn't been read his rights. That is, he hadn't been given the Miranda warning [source: Johnson].

And then confusion: Was it a hitch? What about the confession? Did that mean he would be released? Did the Miranda rights even apply in this case?

The intention behind the Miranda law is straightforward, but its implementation is sometimes not. It goes back to a 1966 U.S. Supreme Court decision in the case Miranda v. Arizona, an appeal of the 1963 rape and murder convictions of Ernesto Miranda. Miranda, like Tsarnaev, had confessed to the crimes in question. Also like Tsarnaev, Miranda hadn't been read his rights before he confessed.

Though technically, there was no such thing as being "read his rights" until Miranda's appeal reached the U.S. Supreme Court.

The Fifth Amendment to the U.S. Constitution includes this statement: "[no one] shall be compelled in any criminal case to be a witness against himself." This is the right against self-incrimination, a cornerstone of the U.S. justice system. Basically, it means anything a suspect says to police must be voluntary in order to be used against him in court.

Before 1966, "voluntary" was a relatively subjective standard.

In 1963, Phoenix police picked up Ernesto Miranda for questioning in the kidnapping and rape of a young woman. In the course of a two-hour interrogation, Miranda confessed to the crimes. He had not been warned of his right against self-incrimination. His confession was admitted as evidence at trial, and Miranda was convicted and sentenced to 20 to 30 years in prison [source: United States Courts].

Miranda v. Arizona was appealed all the way to the U.S. Supreme Court, where the central question before the justices was this: Did the police's failure to warn Miranda of his right to remain silent violate his Fifth Amendment right against self-incrimination, making his confession involuntary and therefore inadmissible at trial?

In a 5-4 decision, the court found that Miranda had, in fact, been denied his constitutional right, stating, in part:

" ... the prosecution may not use statements, whether exculpatory or inculpatory, stemming from custodial interrogation of the defendant unless it demonstrates the use of procedural safeguards effective to secure the privilege against self-incrimination. By custodial interrogation, we mean questioning initiated by law enforcement officers after a person has been taken into custody or otherwise deprived of his freedom of action in any significant way."

The court's decision established a couple of key legal points: that the right against self-incrimination takes effect from the moment a suspect is in police custody, not just at trial; and that any confession obtained without the suspect being explicitly warned of this right is involuntary. Therefore, the court held, a defendant had to be informed of his rights before being interrogated if his statements were to be admissible in court [source: Oyez]. Since that 1966 ruling, a voluntary confession made in police custody is one preceded by a reading of the Miranda rights:

1. You have the right to remain silent.

2. Anything you say can be used against you in a court of law.

3. You have the right to an attorney.

4. If you can't afford an attorney, one will be appointed for you.

And since that ruling, questions have swirled around the law, most of them related to three words in the court's decision: "Taken into custody."

Many law-enforcement agencies throughout the country have since added a fifth warning to the court-established rights, which states, "If you waive these rights, you may still invoke them at a later time."

More that 50 years on, some people think the Miranda warning has not worked as well as it should. One study showed 80 percent of suspects waive their rights and talk to police [source: Kamisar]. Why is that? It might be the manner in which the warning is delivered — or not delivered. Sometimes police interrogate suspects before asking them if they wish to waive rights. Or a policeman might imply that the suspect will get a more lenient sentence if he talks now, rather than gets an attorney first. Other times a suspect feels she can explain herself and make the situation "go away."

The circumstances under which Miranda applies are clear: If a suspect makes a statement during custodial interrogation, it can only be used against him if he was first read his rights and waived them [source: FindLaw]. The court's reasoning for the distinction between custodial and noncustodial questioning, as stated in the 1966 ruling, is that " the process of in-custody interrogation ... contains inherently compelling pressures which work to undermine the individual's will to resist and to compel him to speak where he would not otherwise do so freely" [source: Justia].

The Miranda requirement establishes a way to prove, to a legal standard, that statements made in custody were made voluntarily. The problem is, "in custody" can be slippery. The Miranda decision defines it as the denial of complete freedom of action, a criterion open to interpretation [source: Rydholm].

Sometimes, being in custody is obvious. Under arrest? Sitting in a locked police car? Wearing handcuffs? In custody. Under any of those conditions, Miranda rights must be read before police start asking questions if they hope to have any of the answers admitted as evidence at trial.

Sometimes it's fuzzy, though. What if police arrive at a subject's home to ask him about a crime that happened down the block, and the subject doesn't feel free to leave (or ask the police to do so)?

Over the years, court decisions have helped to clarify some of the uncertainty. In the preceding example, the subject likely would not have been considered in custody, since he wasn't under arrest and therefore could have told the officers to leave at any time; the perception of the subject is not a factor. Traffic stops, too, are noncustodial. If a routine traffic stop yields an unelicited statement not preceded by Miranda warnings, it may be used in court [source: National Paralegal College].

Let's say, though, a suspect is clearly in custody. Police have arrested a woman for selling drugs, and they question her. She confesses. She wasn't read her rights. What happens?

She's not released. But the prosecutor can't use the confession as evidence at the woman's trial. And if that confession led directly to any other incriminating evidence, and that evidence would likely not have been uncovered by police without information gleaned from the confession, that evidence is out, too [source: NOLO]. It's "fruit of the poisonous tree."

There's only one exception to this, and it was invoked under serious public scrutiny in 2013.

The public safety exception allows law enforcement to question a subject, and the prosecution to use his answers against him at trial, even if he wasn't read his rights. To be clear, it's not that someone posing a threat to public safety doesn't have constitutional rights; it's that the threat to public safety has been determined to trump them [source: Rydholm].

The exemption was established in 1984, when the U.S. Supreme Court heard the appeal of New York v. Quarles. Benjamin Quarles was in the custody of police in a grocery store in 1980 when he was identified by a rape victim as the man who'd assaulted her. The officer frisked him for weapons and found an empty gun holster. The officer asked Quarles where the gun was, and Quarles told him he'd hidden it "over there," pointing to an empty milk container. The officer found it and secured it. He then arrested the man and read him his Miranda rights.

The gun evidence was thrown out at trial under Miranda. An appellate court agreed it was inadmissible. The Supreme Court did not.

The Supreme Court found that locating the missing gun was critical to securing public safety, and questions prompted by a reasonable concern for public safety were exempt from the Miranda requirement. Quarles' answer to the officer's question and the gun it led to were therefore admissible in court [source: Rydholm].

In April 2013, the FBI invoked this exemption in questioning a suspect in the Boston Marathon bombing. During their "urgent public safety interview" with Dzhokhar Tsarnaev in his hospital room, he confessed to the bombing and answered questions regarding any other attacks still in the works. His request for a lawyer was denied several times. After two days of questioning, Tsarnaev was read his Miranda rights on a judge's orders and went silent. He was sentenced to death in 2015, though an appeals court overturned the sentence in 2020 [source: Associated Press].

The same exception was invoked in the 2010 questioning of Faisal Shahzad, who failed in his attempt to bomb New York City's Times Square. But Shahzad, after being Mirandized, kept talking -- and never stopped [source: Johnson].

He pleaded guilty at trial, warned Americans to brace themselves for more attacks, and was sentenced to life in prison [source: Katersky]. The public safety exception never came up.

With terrorism on the rise across the nation and world, many Americans believe it's acceptable to deprive suspected terrorists of various civil rights, such as the Miranda rights. Whether the Supreme Court — with a conservative majority in 2020 — eventually chips away at these rights remains to be seen [source: American Psychological Association].
