The Aussie is a whiny little baby. For one, he doesn't even live here. Two, if people weren't flying drones in the way of planes and helicopters, and crashing them into the stands at sporting events, these regulations wouldn't even be necessary. Three, the analogy between the registering of drones being the same as the registering of sex offenders is retarded. Otherwise, every time you have to register anything, like your car, your motorcycle, your boat, your private plane, your marriage, your voting ability, then it's exactly the same as registering as a sex offender.
A better analogy is to registering your car. If you want to drive a car on the public roadways, you have to register it. If you want to fly an unmanned aircraft system outdoors, you have to register it. Same thing.
