What job puts you at the greatest risk of being killed by a violent criminal act? Driving a taxi or chauffeuring clients around town, according to the Bureau of Labor Statistics.

In 1998, there were almost 18 homicides per 100,000 taxicab drivers and chauffeurs — a rate 36 times higher than experienced by the total U.S. workforce.

Public police and detectives suffered the second-highest occupational fatality rate from homicide, 4.4 fatalities per 100,000 workers.
