What is the consequence of failing to provide a Miranda warning?

When law enforcement officers fail to provide a Miranda warning, any statements or confessions made by a suspect during a custodial interrogation may be deemed inadmissible in court. This principle stems from the Fifth Amendment of the U.S. Constitution, which protects individuals from self-incrimination. The Miranda warning, which informs a suspect of their rights to remain silent and to have an attorney present during questioning, is crucial for preserving the validity of any statements made thereafter.

When a suspect has not been informed of their rights, any statement they make can be challenged in court, as it may not have been made voluntarily or with full awareness of the consequences. This rule is intended to prevent coercion and to safeguard the rights of individuals in custody. As a result, if the Miranda warning is not provided when required, it significantly impacts the admissibility of evidence and the fairness of the legal proceedings.
