Interrogation Law and Legal Definition

Interrogation is, in criminal law, the process of questions asked by police to a person arrested or suspected to seek answers to a crime. Such person is entitled to be informed of his rights, including right to have counsel present, and the consequences of his answers. If the police fail or neglect to give these warnings, the questions and answers are not admissible in evidence a the trial or hearing of the arrested person.

The United States Constitution establishes the legal foundation controlling police interrogation. The Fifth Amendment guarantees the suspect's right against self-incrimination. The Sixth Amendment expressly guarantees his right to counsel in a criminal proceeding.
