Under British law, a police officer must now say the following to a suspect placed under arrest: “You do not have to say anything. But if you do not mention now something which you later use in your defense, the court may decide that your failure to mention it now strengthens the case against you. A record will be made of anything you say and it may be given in evidence if you are brought to trial.” What is the goal of this British law? What does a police officer in the United States have to say, and what difference does it make at the time of an arrest? Which approach is better?
