Don't read this if you are easily disturbed, the stories in this report are gutwrenching.

In April a BMW racing through a fruit market in Foshan in China’s Guangdong province knocked down a 2-year-old girl and rolled over her head. As the girl’s grandmother shouted, “Stop! You’ve hit a child!” the BMW’s driver paused, then switched into reverse and backed up over the girl. The woman at the wheel drove forward once more, crushing the girl for a third time. When she finally got out from the BMW, the unlicensed driver immediately offered the horrified family a deal: “Don’t say that I was driving the car,” she said. “Say it was my husband. We can give you money.”
“Double-hit cases” have been around for decades. I first heard of the “hit-to-kill” phenomenon in Taiwan in the mid-1990s when I was working there as an English teacher. A fellow teacher would drive us to classes. After one near-miss of a motorcyclist, he said, “If I hit someone, I’ll hit him again and make sure he’s dead.” Enjoying my shock, he explained that in Taiwan, if you cripple a man, you pay for the injured person’s care for a lifetime. But if you kill the person, you “only have to pay once, like a burial fee.” He insisted he was serious—and that this was common.
Here too, the driver was charged only with accidentally causing a person’s death. (He claimed to have confused the boy with a cardboard box or trash bag.) Police rejected charges of murder and even of fleeing the scene of the crime, ignoring the fact that the driver ran over the boy’s head as he sped away.

These drivers are willing to kill not only because it is cheaper, but also because they expect to escape murder charges. In the days before video cameras became widespread, it was rare to have evidence that a driver hit the victim twice. Even in today’s age of cellphone cameras, drivers seem confident that they can either bribe local officials or hire a lawyer to evade murder charges.
