Traffic Signal Prankster

A prankster in Sunnyvale, California has been toying with traffic lights across the city for three months. Police say he or she has turned them to face the wrong way, altered the timing, and made them flash red in all directions. There is evidence that whoever is doing it knows what they’re doing, (city spokesman John) Pilger said. The evidence suggests they’re an electrician or have that background.
