The Fifth Amendment in the Bill of Rights is an important part of the United States Constitution because it protects certain individual liberties by restricting federal governmental power. The Fifth Amendment’s protections against self-incrimination prohibit American law enforcement from compelling people to speak during criminal investigations.
The clause states in part that no person shall be compelled in a criminal case to be a witness against themself. This means that a person should not be forced to provide evidence that could incriminate oneself.

In Miranda v. Arizona, the Supreme Court held that any statement made in a custodial interrogation cannot be used against a suspect unless the police informed the suspect of their right against self incrimination.
Miranda warnings have to be given whenever a suspect is interrogated while under arrest. The Miranda case is the origin of the requirement that law enforcement officers must inform people of their “Miranda rights” as part of their Fifth Amendment right to remain silent. The Miranda case changed how interrogations are conducted.
Miranda warnings are generally provided to suspects while they are being arrested, taken into custody, while they are being moved from one location to another, or otherwise deprived of their freedom of action.
Miranda warnings can be given at any time during an interrogation. However, if the suspect indicates that they would like to remain silent or speak with a representative of their choice (typically a lawyer), then law enforcement can no longer question a person about the crime they were arrested for.
Conversely, under Miranda , if a person indicates that they want to waive their right to remain silent, law enforcement can continue questioning until and unless the person clearly requests an attorney.
Miranda applies whether or not it has already been determined that the person is a suspect. By requiring Miranda warnings to be read whenever a person is arrested, the Court intended to prevent police from using coercive tactics to force confessions from suspects in custody.
