I read a similar article about that. The restrictions made it sound like you can only shoot at police/military drones at low altitudes. Which they wouldn't fly at such low altitudes. Basically, my impression was that it wouldn't be possible to actually shoot anything down and it's just a way for the town to make money off of paranoid idiots.
I didn't read this article, but the one I did read said that if you shoot down some one's personal property, the shooter has to pay for a replacement.
