D, requires that suspects be read their rights before questioning. Have you ever watched a movie or a TV show and you watch someone get arrested? You know how, as the cops are putting the handcuffs on the suspect, they say something like "So-and-so, you are under arrest for (whatever crime they did). Everything you say can and will be used against you in a court of law. You have the right to an attorney. If you cannot afford one, one will be appointed to you by the court." You know, that? That's the Miranda rule and those rights are known as the Miranda rights.
