Interrogation

Vigorous questioning, usually by the police of a suspect in custody. Other than providing their names and addresses, suspects are not obligated to answer the questions, which must be preceded by Miranda warnings. When suspects refuse to answer, their silence generally cannot be used by the prosecution to help prove that they are guilty of a crime. If the suspect has asked for a lawyer, the police must cease questioning. If they continue to question, they usually cannot use the answers against the suspect at trial. (See also: Miranda warnings)
