Last week, Liz Dwyer got a phone call that nobody ever wants to get. Her husband, Elarryo Bolden, had been hit by a truck while riding his bike. The driver fled the scene. Elarryo’s injuries turned out to be minor. But unfortunately, many victims of similar hit-and-runs each year aren’t so lucky. Los Angeles has been called the country’s hit and run capital. Twenty-thousand hit-and-run accidents happen in the city every year. Last year, 144 people were seriously injured and 27 were killed by drivers who didn’t stop. Yet only about 1 in 10 hit-and-run drivers are ever arrested or prosecuted. Why can’t the city get a handle on this problem?
