John Goglia has a piece on Forbes.com stateing that the FAA has responded to questions about the shooting down of drones. Citing 18 U.S.C. 32, the FAA has confirmed that shooting down a Drone or any other aircraft is a felony. This statue goes on further and prohibits interfering with anyone “engaged in the authorized operation of such aircraft”. This means that threatening a drone or drone operator could put a person in jail for 5 years.
While the FAA says that it is a federal crime to shoot down aircraft, they have not stated when they will start prosecuting those that are shooting down UAVs
