are in Brooklyn. Another form of automobile insurance fraud, known as "fronting", involves registering someone other than the real primary driver of a car as the primary driver of the car. For example, parents might list themselves as the primary driver of their children's vehicles to avoid young driver premiums. "Crash for cash" scams may involve random unaware strangers, set to appear as the perpetrators of the orchestrated crashes. Such techniques are the classic rear-end shunt (the driver in front suddenly slams on the brakes, possibly with brake lights disabled), the decoy rear-end shunt (when following one car, another one pulls in front of it, causing it to brake sharply, then the first car drives off) or the helpful wave shunt (the driver is waved into a line of queuing traffic by the scammer who promptly crashes, then denies waving). Organized crime rings can also be involved in auto-insurance fraud, sometimes carrying out schemes that are very complex. An example of one such ploy is given by Ken Dornstein, author of Accidentally, on Purpose: The Making of a Personal Injury Underworld in America. In this scheme, known as a "swoop-and-squat", one or more drivers in "swoop" cars force an unsuspecting driver into position behind a "squat" car. This squat car, which is usually filled with several passengers, then slows abruptly, forcing the driver of the chosen car to collide with the squat car. The passengers in the squat car then file a claim with the other driver's insurance company. This claim often includes bills for medical treatments that were not necessary or not received. An incident that took place on Golden State Freeway June 17, 1992, brought public attention to the existence of organized crime rings that stage auto accidents for insurance fraud. These schemes generally consist of three different levels. At the top, there are the professionals—doctors or lawyers who diagnose false injuries and/or file fraudulent claims and these earn the bulk of the profits from the fraud. Next are the "cappers" or "runners", the middlemen who obtain the cars to crash, farm out the claims to the professionals at the top, and recruit participants. These participants at the bottom-rung of the scheme are desperate people (poor immigrants or others in need of quick cash) who are paid around US$1000 to place their bodies in the paths of cars and trucks, playing a kind of Russian roulette with their
