There are many very useful applications for drones, personal or otherwise. The genie is out of the bottle.

US Gov't wants to regulate 'em. Hey, go ahead, but it's a waste of time. Too many people want 'em and will have 'em, 'legal' or not.

You can supposedly be prosecuted for shooting down a drone over your property, but it sounds like (and will become) great sport.

A few safety regulations, e.g., airport restrictions, make sense, but after that, anarchy rules.
