If you're stopped by a police officer(s), and feel that their actions are wrong, can you request a supervisor?

Hi J Huk, yes, you can request to speak with the Duty Sargeant or a Supervisor, like a Lieutenant. USUALLY, it can be for most any LOGICAL reason, not for stuff like "the cuffs were too tight" or the "jailer didn't give me a blanket", or my favorite..."My food was tasteless and bland".
