There is no question that on the night of Dec. 13, 1992, at least one of two men arrested in East Flatbush, Brooklyn, violated state gun laws. Lester Smith and Orson Grosse were pulled over by Police Officer Michael Dalton and his partner for a routine traffic violation. In the car the police found a loaded 10-millimeter Glock semiautomatic, a $600 gun. Neither man had a permit. Even if one did, the gun is supposed to be transported unloaded, in a locked box in the trunk.
