Miranda warning

The Miranda warning is a set of rights police must tell a person who is in custody and being questioned. The goal is to protect the person’s Fifth Amendment right against self-incrimination and, in some cases, the Sixth Amendment right to a lawyer. When the warnings are given, the person can choose to speak or stay silent, and any statements they do make can only be used in court if they understood and knowingly waived those rights.

Origins and purpose
- The warnings come from the 1966 Supreme Court case Miranda v. Arizona. The idea is to keep police from pressuring someone into giving up their rights, so the statements made during interrogation can be trustworthy and legally usable in court.
- The exact words aren’t fixed. Different places may use slightly different wording, but the important part is that the rights are clearly explained and understood.

When the warnings must be given
- They apply when someone is in custody (not free to leave) and being questioned or asked questions that are likely to elicit an incriminating response.
- If the person is not in custody or the questions are not likely to elicit a confession, the warnings are not required.

What the warnings typically say
- You have the right to remain silent.
- Anything you say can be used against you in court.
- You have the right to talk to a lawyer for advice before we ask questions.
- You have the right to have a lawyer with you during questioning.
- If you cannot afford a lawyer, one will be appointed for you before any questioning if you wish.
- If you decide to answer questions now without a lawyer present, you have the right to stop answering at any time.

Important ideas about understanding and waiving rights
- The warnings must be meaningful. The officer should check that the person understands their rights. In some places, officers may ask “Do you understand?” after the warning.
- Waiver means the person agrees to talk despite the rights. For a waiver to be valid, it must be knowing, voluntary, and intelligent. If police used coercion, the waiver may be invalid and the statements could be excluded in court.
- A waiver can be written or spoken. If the person initially says they don’t understand or don’t want to talk, the interrogation usually stops or the warnings are refreshed before any questioning continues.
- If the person asks for a lawyer, interrogation must stop until the lawyer is present (or the person explicitly waives the right again).

Invoking rights and continuing questioning
- If the person says they want to remain silent, questioning must stop immediately until they resume with a valid waiver.
- If the person asks for a lawyer, interrogation stops and cannot resume until a lawyer is present or the person chooses to speak again with a new waiver.
- If the person says they want to talk but then changes their mind, officers may try to clarify, but they must respect a clear, unequivocal change in mind.

Exceptions and other protections
- There are a few limited exceptions to Miranda. For example, routine administrative questions at the time of arrest aren’t treated as interrogation for Miranda purposes. The “public safety” exception allows some urgent questions to be asked without warnings if there’s an immediate danger to the public.
- Even when Miranda warnings apply, other laws can affect how statements and evidence are used. For instance, separate rules may apply to the use of a suspect’s statements versus physical evidence like a weapon found as a result of those statements.
- The warnings also relate to other constitutional rules, such as the Massiah doctrine (which deals with the Sixth Amendment right to counsel during later stages of prosecution) and issues about the voluntariness of a confession.

Extra notes
- If a person does speak after being Miranda-warned, a judge will look at whether the waiver was voluntary and informed. If not, the statements may be excluded.
- Language barriers can matter. If someone doesn’t understand English well, officers should provide translation or explanation so the person can understand their rights.
- Miranda rights generally apply to U.S. citizens and non-citizens alike when they are in custody and being questioned in a way likely to produce information about a crime.

In short, the Miranda warning is meant to ensure that anyone in police custody understands their right to stay silent and to have a lawyer, and that any decision to talk is voluntary and informed.
