BRENDAN I. KOERNER — An ABC affiliate in Omaha has a how-to on challenging speeding tickets based on laser-gun readings. Lasers guns, like their radar predecessors, aren’t quite as infallible as the manufacturers would have the fuzz believe, especially if tune-ups are few and far between. The Nebraskan advice seems sound, though you’ll need some major cojones to ask the cop for the name of his gun’s manufacturer. If you come across a tough S.O.B. whose wife just split, he might reward your insolence with a rough patdown and a vehicle search. And years of watching Cops has taught me this: Explaining that the roach in the ashtray belongs to your cousin just doesn’t work.
