What case law requires reading a subject their rights before interrogation?

The requirement to read a subject their rights before interrogation comes from the landmark case of Miranda v. Arizona. In this case, the U.S. Supreme Court established that individuals taken into police custody must be informed of their rights, specifically the right to remain silent and the right to an attorney, before any questioning occurs. This decision was rooted in the Fifth Amendment, which protects against self-incrimination, ensuring that individuals are fully aware of their rights and the consequences of waiving them.

This standard is crucial for ensuring that confessions or admissions made during interrogation are obtained voluntarily and with an understanding of the individual’s rights. If a subject is not informed of these rights, any statements they make during interrogation may be deemed inadmissible in court. Thus, the Miranda warning has become a vital part of police procedure in the United States to uphold constitutional protections for those in custody.
