You may be powerless to stop a drone from hovering over your own yard

"Some argue the agency has the legal authority to address the privacy issues raised by drones. But the agency “does not consider privacy to be their role or expertise,” said University of Washington law professor Ryan Calo.

For now, everyday homeowners mostly have to depend on local laws to fend off drones. In some cases, homeowners could bring civil cases against the pilots of low flying drones, according to Calo. They may also be able to persuade local law enforcement to bring charges against the operators under existing trespass, nuisance or “peeping Tom” laws."
