Concern over highway spy-eyes goes national

The Wall Street Journal clues in to a concern near and dear to our Arizona hearts: traffic cameras.

Once a rarity, traffic cameras are filming away across the country. And they're not just focusing their sights on red-light runners. The latest technology includes cameras that keep tabs on highways to catch speeders in the act and infrared license-plate readers that nab ticket and tax scofflaws.

Drivers -- many accusing law enforcement of using spy tactics to trap unsuspecting citizens -- are fighting back with everything from pick axes to camera-blocking Santa Clauses. They're moving beyond radar detectors and CB radios to wage their own tech war against detection, using sprays that promise to blur license numbers and Web sites that plot the cameras' locations and offer tips to beat them.

That's an issue I've given a nod or two in the past myself, of course.
