The FAA and AMA guidelines are laughably worthless. No one takes flying model aircraft/drones seriously with regards to public safety. They are flown all the time in parks with lots of people around who could be seriously hurt. The park rangers don't care. If you approach the pilot they just berate you and tell you to mind your own business.
In my city there are three airports who's five mile circles all intersect and involve the complete metropolitan area. Drones and RC aircraft are flying all the time.
No one enforces the dog leash laws so why on earth will they care about model aircraft?
