brilliant cop I came across this morning... he's not chasing violators, he's just letting them come to him

The cop just waited in the middle on the jammed up on ramp, and every stupid person with a cell phone to their ear, or their seat belt off were pointed off to the side, and then gave tickets. Zero effort, maximum effect. Why in the hell aren't more cops this smart? If you want to stop cell phones users, and seat belt scoffers.... hell, even cracked windshields, bald tires, and whatever the rest of the simple visual moving violations there are to see
