The motorcycle cop we just saw earlier catches up to the car and gestures for the driver to pull over. The driver pulls off onto a side street at the next exit, and comes to a stop. The cop walks up to the car and asks the driver for his license, telling him that he illegally crossed a double-white line. At Ricca's attorney's urging, the driver reluctantly hands over his license. The cop goes back to his bike, supposedly to write down information in his ticket book. After a few minutes, he returns and asks the driver for his vehicle registration. The driver asks to get his license back. In response, the cop suddenly whips his revolver out and shoots the limo driver in the side of the face. He then shoots the bodyguard in the passenger's seat as he tries to draw a pistol.
