If you’re arrested, you have the right to remain silent. There is no legal reason to speak to a police officer if you don’t wish to – especially since anything you say ‘can and will be used against you’ – but never walk away from an officer until given permission. All persons who are arrested have the legal right to make one phone call. If you don’t have a lawyer or family member to help you, call your consulate. The police will give you the number upon request.
