The Supreme Court recently confirmed that Miranda warnings are constitutionally required because of a 1966 case called Miranda v Arizona. If you give up the right to remain silent, anything you say can and will be used against you in a court of law. You have the right to an attorney. If you desire an attorney and cannot afford one, an attorney will be obtained for you before police questioning. The Miranda rule was developed to protect the individual's Fifth Amendment right against self-incrimination.
Many people feel obligated to respond to police questioning.
The Miranda warning ensures that people in custody realize they do not have to talk to the police and that they have the right to the presence of an attorney. If the Miranda warning is not given before questioning, or if police continue to question a suspect after he or she indicates in any manner a desire to consult with an attorney before speaking, statements by the suspect generally are inadmissible. However, it may be difficult for your attorney to suppress your statement or confession in court. The best rule is to remain silent. You have the right to an attorney.
