And what will the “feds” do if they disobey?
NOTHING!
F U B O!
That is a good point.
As a former fed with DOJ and Homeland Security, we never had citation ability. We had no ticket book to issue a citation everything had to go to federal court.
I am not sure about the National Park Service. If they do have the ability and write up a bunch of people for say trespassing, they would quickly clog the federal court system if the violators demanded their day in court.
You would probably get a court date of 2020 at this point.
