Police only need to provide Miranda warnings in certain situations. Learn when Miranda rights are required and what happens if police don't follow the law.If police question you AFTER arrest without reading your rights to you, the information you provide may be inadmissible as evidence against you. Contrary to what many believe, you can be arrested, taken to jail, prosecuted, and even convicted without ever hearing a single word about your Miranda rights. While Miranda warnings are extremely important, an officer's failure to read them in and of itself does not result in a dismissal of criminal charges. Police must read you your Miranda rights when arresting you or holding you for custodial interrogation (even if you haven't been charged). You may not have been read Miranda rights if you were not being taken into custody to be interrogated or put under arrest. No. You are required to read Miranda rights to someone in custody when asking them questions. If you want answers admissible in court, anyway. Miranda rights are things you are legally entitled to upon being arrested.
