WASHINGTON – 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.
