If the officers tell you that you are under arrest, do not fight. This will only add to your problems. Simply go with them and follow their instructions. You do not want to make them upset and hurt your chances of a better outcome.
Do Not Answer Questions
Officers will want to perform an initial investigation on scene. You have nothing to gain by telling them anything. Your words will be changed around and used against you. Even if you have not been cuffed, you still should not answer questions without an attorney present.
Assert Your Right to Remain Silent and Your Right to an Attorney
This step requires little explanation. The Constitution guarantees you both of these rights, so use them. Officers will promise the moon to you, but they will only deliver large periods of confinement.
