Here's a hypothetical scenario for you.
You respond for a call from SWAT, they have a pregnant 15 year old in custody complaining of abdominal pain after some minor trauma during the arrest process. She is currently in police custody and wishes transport for evaluation. While on scene PD decides they are not going to charge her with anything and are releasing her. She suddenly changes her mind and does not want transport or any further care from you. She wants to walk back to her aunts house where she stays.
What do you do?
