It has to be a civilian opperation, no local, county state or federal oversight or control.
It's a good idea. Though to allow that much control over our air-space for law enforcement to actually conduct endless "spying" operations on populations is creepy at best. At its worst I can see the slipery slope of abuse.
We should allow for private ownership and operation for drones. They would in turn lease air time video feeds to enforcement agancies, Conduct special opperations etc etc. All under the supervision of civilian privately owned "Drone" companies.
No level of government agency should be allowed to opperate spying opperations on civilians ,at random, useing Drones. Spy-Drones should only be allowed under a court order just like a search warrant. Wherein proof of a crime or potential crime must be submitted as probable cause to obtain a search warrant.
No Drones with weapons sould be allowed to be flown within the borders of the USA.
