Just for clarities sake and because people should understand their rights. 1. The police have no obligation to read you your Miranda rights. They never have. Journalist don't seem to understand this and there are many lawyers and even a few judges who seem to not comprehend this. The Supreme Court has consistently supported this view time and again, many justices on the Supreme Court believe that Miranda was a bad ruling which they have chosen to live with. 2. Failure to read you your Miranda rights means that things you say can't be used against you in court proceedings. 3. Evidence gained from an interrogation where Miranda hasn't been invoked can be used against in court proceedings as long as it's not the actual speech of the accused. Warrants can be issued as a result of information gained from interrogations from non-Mirandized suspects. 4. Your best bet is to keep your yap shut regardless of weather you have been read your rights or not.
