WASHINGTON (AP) - Thousands of drones patrolling U.S. skies?
Predictions that multitudes of unmanned aircraft could be flying here within a decade are raising the specter of a "surveillance society" in which no home or backyard would be off limits to prying eyes overhead. Law enforcement, oil companies, farmers, real estate agents and many others have seen the technology that was pioneered on battlefields, and they are eager to put it to use.
It's not just talk: The government is in the early stages of devising rules for the unmanned aircraft.
A ShadowHawk drone is guarded by a Montgomery County, Texas, SWAT team member.
So far, civilian use of drones is fairly limited. The Federal Aviation Administration had issued fewer than 300 permits for drones by the end of last year.
Public worries about drones began mostly on the political margins, but there are signs that they're going mainstream.
Jeff Landry, a freshman Republican congressman from Louisiana's coastal bayou country, says constituents have stopped him while shopping at Walmart to talk about their concerns.
"There is a distrust amongst the people who have come and discussed this issue with me about our government," Landry said. "It's raising an alarm with the American public."
Fear that some drones may be armed, for example, has been fueled in part by a county sheriff's office in Texas that used a homeland security grant to buy a $300,000, 50-pound ShadowHawk helicopter drone for its SWAT team. The drone can be equipped with a 40mm grenade launcher and a 12-gauge shotgun.
Randy McDaniel, chief deputy with the Montgomery County Sheriff's Office, told The Associated Press earlier this year his office had no plans to arm the drone, but he left open the possibility the agency might decide to adapt the drone to fire tear gas canisters and rubber bullets.
Earlier this year Congress, under pressure from the Defense Department and drone manufacturers, ordered the FAA to give drones greater access to civilian airspace by 2015. Besides the military, the mandate applies to drones operated by private companies or individuals and civilian government agencies, including federal, state and local law enforcement.
The military, which is bringing home unmanned aircraft from Afghanistan, wants room to test and use them.
But the potential civilian market for drones may far eclipse military demand. Power companies want them to monitor transmission lines. Farmers want to fly them over fields to detect which crops need water. Ranchers want them to count cows. Journalists are exploring drones' newsgathering potential. Police departments want them to chase crooks, conduct search and rescue missions and catch speeders.
But concern is spreading. Another GOP freshman, Rep. Austin Scott, said he first learned of the issue when someone shouted out a question about drones at a Republican Party meeting in his Georgia district two months ago.
There's concern among civil liberties advocates that government and private-sector drones will be used to gather information on Americans without their knowledge. Giving drones greater access to U.S. skies moves the nation closer to "a surveillance society in which our every move is monitored, tracked, recorded and scrutinized by the authorities," the American Civil Liberties Union declared last December.
The concern has spilled into Congress, where lawmakers from both parties have been meeting to discuss legislation that would broadly address the civil-liberty issues. A Landry provision in a defense spending bill would prohibit information gathered by military drones without a warrant from being used as evidence in court.
