More On Domestic Drones

All Things Considered:

While law enforcement is a big market for makers of unmanned aircraft systems — known as UAS's — there are many other potential civilian users.
Gretchen West is with the Association for Unmanned Vehicle Systems International, an industry trade group.
"Utility companies — so oil and gas — [are] using a UAS to do surveillance over a pipeline," she says, as are electrical companies wanting to watch over their electrical wires. West says drones can be used for crop-dusting and tracking livestock. They've already been used for flood mapping in North Dakota, and they could also be used for weather research.
But all those unmanned aircraft have some people a little wary. Privacy advocate Harley Geiger of the Center for Democracy and Technology says drones are basically flying video cameras.
"Drones can easily be equipped with facial recognition cameras, infrared cameras or open Wi-Fi sniffers," Geiger says. "So when people think about drones they shouldn't just think that a telephoto lens is the only feature that can raise a privacy issue."
Nor, says Geiger, is it only law enforcement that could be watching: "The paparazzi, your homeowners' association, your neighbor, a journalist can all sic drones on you as well."

Sounds like a mess.  I bet the FBI will be is using these things to track, say, war protesters or the Occupy folks.
