Opinion - Smile, Big Brother is watching

Surveillance cameras are everywhere. They have become a symbol of this new world.

Nearly any crime story shows some victim or suspect tracking through a store, an airport or a back alley. Videos of missing persons and convenience store robberies are daily fare.

Even roads and highways are spotted with cameras. Cameras on traffic signals catch a motorists running a red light.

And, of course, it is unlikely that any large retail store is without its own surveillance system scanning every aisle and every space in the parking lot. Those little bubbles on the ceilings are not smoke detectors.

Good...
