Before Janet Napolitano, secretary of the Department of Homeland Security, unleashed full-body-imaging scanners and "enhanced" pat-downs on American airline passengers, she subjected Arizona drivers to red-light cameras. In August 2008, Napolitano, then the governor of Arizona, instituted a statewide system of 200 fixed and mobile speed and red-light cameras, which were projected to bring in more than $120 million in annual revenue for the state. She was aided in this endeavor by the Australian corporation Redflex Traffic Systems.
Two years later, after widespread complaints that the cameras intrude on privacy and are primarily a money-making enterprise for the state (income actually fell short of the projections because people refused to pay their fines), Arizona put the brakes on the program. And while other states - including Maine, Mississippi, Montana, Nevada, New Hampshire, West Virginia, and Wisconsin - have since followed suit, many more municipalities, suffering from budget crises, have succumbed to the promise of easy revenue and installed the cameras. (Davenport began using red-light cameras in 2004.) As the Washington Post notes: "A handful of cities used them a decade ago. Now they're in more than 400, spread across two dozen states. Montgomery County started out with 18 cameras in 2007. Now it has 119. Maryland just took the program statewide last month, and Prince George's is putting up 50. The District started out with a few red light cameras in 1999; now they send out as many automated tickets each year as they have residents, about 580,000."
