The drivers remained behind the wheels of the armored vehicles while four men stepped into the road, began looking over the cars on the street, the people passing by. The men wore black Italian-cut business suits, their hands were empty, they were quick and efficient with their movements, but they were not impolite as they moved through the foot traffic to the front door of the restaurant. There they stood, back to the wall, and they all unbuttoned their coats. Their eyes scanned the street in all directions. Three Guadalajara police squad cars double-parked on the street. Their flashing lights reflected off the glass for a block in each direction. A pair of patrolmen stepped out of each vehicle and began directing traffic to continue on up the street. No one would be allowed to park anywhere near the front of the restaurant. Four more men climbed out of the gleaming white SUVs and moved directly through the bronze double doors of the restaurant. These men wore black suits as well, carried handheld radios and empty black nylon bags.
