Orders of Protections, Injunctions Prohibiting Harassment, etc.
If a judge, justice, or magistrate issues one a court order to cease and desist - it is a darn good idea to observe that order to the letter. Judicial officers have very little tolerance for people who ignore and violate their orders.
Trying to claim an exemption due to Federal oversight of the RF spectrum is a waste of time. One might as well claim that the state authorities have no jurisdiction over bank robberies because the bank robbed was a Federally chartered financial institution, is FDIC insured, and because the Federal Reserve printed the currency involved.
As to jail time, it is perfectly appropriate. Jails are for misdemeanors and prisons are for felonies. What one state decides to do with their felony prison population has no effect on what a county in another state decides to do with someone sentenced to serve time under a conviction for a misdemeanor.
