Do I have to answer questions that the police ask me before or after I'm arrested?

No. You have a right not to say anything at all even if the police ask you questions either before or after you are arrested. Don't be afraid to remain silent. Anything you do say, in answer to questions, may be used in court later to try to show that you're guilty. The police may promise that things will go better for you if you talk but that is usually not what happens. It will be hard to prove to a judge that the police made this promise to you if it is not in writing. If you are under 16 and the police can get in touch with your parent or guardian, the police are supposed to make sure that your parent or guardian is there when the police read you your rights and question you.
