First and foremost, you should remember your right to remain silent. Officers are serious when they tell you that anything you say can and will be used against you in court.  Probably the most common mistake made by anyone following an arrest is the decision not to remain silent.  Confessions make up a significant portion of all convictions.  You also have the right to have an attorney present during questioning. This does not mean the officers have to stop their investigation to wait for the arrival of an attorney to oversee what they are doing, but they cannot ask you questions without an attorney being present, if you invoke your right to one. Once you have identified yourself, you may refuse to make any statement or discuss the case with anyone. On the other hand, you may choose to answer questions or sign papers. Keep in mind, any information you give can be used as evidence against you in court. Law enforcement officers cannot force or threaten you into answering questions and cannot offer leniency in exchange for any written or oral statements. If you want to remain silent and end an interrogation you have to break your silence and state unequivocally that you are invoking your right to an attorney and will not answer any further questions. Otherwise the police can continue asking questions of a person who refuses to talk as long as the police want, in hopes that the person will eventually give them some information.
