"I'll be watching you"

Automatic surveillance has gotten cheap and powerful enough that the police can keep an eye on everyone, 24 hours a day.

We have arrived at a unique moment in the history of surveillance. The price of both megapixels and gigabytes has plummeted, making it possible to collect a previously unimaginable quantity and quality of data. Advances in processing power and software, meanwhile, are beginning to allow computers to surmount the greatest limitation of traditional surveillance—the ability of eyeballs to effectively observe the activity on dozens of video screens simultaneously. Computers can't do all the work by themselves, but they can expand the capabilities of humans exponentially.

Liberty Island, name notwithstanding, is one of the most heavily surveilled places in America. Dozens of cameras record hundreds of hours of video daily, a volume that strains the monitoring capability of guards. The National Park Service has enlisted extra help, and as Emma and I strolled around, we weren't just being watched by people. We were being watched by machines.

Liberty Island's video cameras all feed into a computer system. The park doesn't disclose details, but fully equipped, the system is capable of running software that analyzes the imagery and automatically alerts human overseers to any suspicious events. The software can spot when somebody abandons a bag or backpack. It has the ability to discern between ferryboats, which are allowed to approach the island, and private vessels, which are not. And it can count bodies, detecting if somebody is trying to stay on the island after closing, or assessing when people are grouped too tightly together, which might indicate a fight or gang activity. "A camera with artificial intelligence can be there 24/7, doesn't need a bathroom break, doesn't need a lunch break and doesn't go on vacation," says Ian Ehrenberg, former vice president of Nice Systems, the program's developer.

And it's not just the police who'll be watching. It's everyone.

...I cruised the aisles of the neighborhood grocery store, a Pathmark, tossing items into my cart like a normal shopper would—Frosted Mini-Wheats, Pledge Wipes, a bag of carrots. Then I put them on the belt at checkout. My secret was on the lower level of the cart: a 12-pack of beer, concealed and undetectable. Or so I thought. Midway through checkout the cashier addressed me, no malice in her voice, but no doubt either. "Do you want to ring up that beer?"

...

(I know of a local pizzeria that warns customers with a posted sign: "Stop stealing the spice shakers! We know who you are, we have 24-hour surveillance!")

And by "everyone", I mean everyone

...As this month's cover story notes, the recent boom in video monitoring—by both the state and businesses—means we're all being watched. It's like something out of George Orwell's 1984. Except that, unlike Orwell's protagonist Winston Smith, we can watch back—and plenty of people are doing just that. Which makes a difference.

...

Ever since the Rodney King case, police have known that video images—whether recorded by citizens or by the authorities themselves—can provoke controversy. With video technology spreading so rapidly, such images are coming to light more often. In October 2007, an elite unit of the Chicago Police Department was disbanded after video emerged of its members shaking down barroom customers. A policeman in Puerto Rico is under FBI investigation because video—uploaded to YouTube—apparently shows him executing an unarmed man. And a Baltimore woman recently won a $180,000 false arrest and imprisonment lawsuit based on police videotape evidence that confirmed a different but similarly dressed woman was the one buying drugs.

Supporters of widespread surveillance often argue, "If you're obeying the law, you have nothing to fear." Why shouldn't the same go for police officers?

Why, indeed?
