An anonymous reader writes: Drone lawyer and commercial pilot Jonathan Rupprecht believes any drone registration plan is a necessary first step, but he's also doubtful that registering drones will be a valuable solution. "Who is going to regulate this? Point-of-sale? Wal-Mart? Best Buy?" he asked. "What if I'm ordering parts off the Internet and put them together? That's what the gun industry does." A registration number, he said, could quickly be lost if a drone is bought and sold multiple times. Rupprecht believes geofencing will produce far better results by preventing problems as opposed to trying to figure out who is responsible after something has happened.
