Well, yeah they were.
They are breaking a nonsensical rule arbitrarily imposed by an out of control government agency.
A government agency that has authority for managing the property.
Law is the Constitution. Everything else is a statute or an ordinance.
The Constitution disagrees with you. Article VI: "This Constitution, and the Laws of the United States which shall be made in pursuance thereof...shall be the supreme law of the land; and the judges in every state shall be bound thereby, anything in the constitution or laws of any state to the contrary notwithstanding."
If so you are an idiot.
