Assuming that the order actually SAYS that the teenager gets to choose where he goes and when, it is also a good example of why these are badly written orders. In some/many states (like mine) the police can enforce court-ordered visitation. Since it is a crime to disobey a judge's order (PC 166(a)(4)) failure to follow a custody agreement signed by the court can result in criminal charges and even the compelled transfer of the child. In other states (perhaps the state shown in the video) these orders may not be enforceable by the police and they may have to refer the parties back to the court for sanctions ... admittedly I did not watch the whole video - a few at the front, and a couple when the officer got there, but that was it.
So, don't assume that this video is in any way indicative of the laws in all states, or the options of law enforcement who might respond to such custody matters. But, if the court order states that the minor has the right to make that decision, then such is the order ... though I think that is a baaaaad idea.
