I guess you can go tell the military they are wrong, along with all the homeowners that have been arrested for shooting drones down with shotguns. You might want to do some actual research before just spouting off whatever you think when the facts don't support it. They even make shot shells designed to take down drones.
Yes shooting down a drone is an offense in the US, unless you're in law enforcement or the military in specific situations.
