For motorists in Berkeley, it’s dangerous to roll through a crosswalk occupied by a pedestrian, because he or she just might be a cop. In an effort to protect pedestrians against reckless and impatient drivers, police have set up decoys in local crosswalks. In a recent sting operation, police handed out 34 tickets in an hour and 45 minutes, reports the Berkeley Daily Planet (Sept. 6, 2002).
