A friend was at family dinner last night at his fathers. A bad argument broke out and accusations were made about his wife. She was being blamed for their sons birth defect. He packed up his wife and kids and left before things got physical. The family called the cops claiming he left in a rage and he was a danger to his kids. Cop showed up at his house and ordered him to return to his fathers house so they could all sort everything out. He refused and slammed the door on the cop. Today he finds out he might be facing charges for disobeying the orders of a police officer. A detective is coming today to take his statement. Can a cop order someone to return to a place where no crime was committed? Any suggestions?
