And the LAST place anyone wants to wind up is in Federal Court. First off, you are going to pay a lot of money to get a decent Federal attorney...Because Federal court is an entirely different ball game.
Anyone who has ever had any dealings with ANY federal agency in the US will tell you how it goes. They will win, about 99.9% of the time, because all the laws and regulations are in their favor, and are generally much stricter than state and local rules, regulations and laws.
Believe me, I'm not sticking up for them and some of their rules are ridiculous...but honestly, a LOT of drone fliers are ridiculously dangerous too, unfortunately. YouTube is full of them!!
