Yes, more whites than blacks die as a result of an encounter with police, but whites also represent a much bigger chunk of the total population.
The Centers for Disease Control and Prevention keeps data on fatal injuries from 1999 to 2011 and one category is homicides by legal intervention. The term "legal intervention" covers any situation when a person dies at the hands of anyone authorized to use deadly force in the line of duty.
Over the span of more than a decade, 2,151 whites died by being shot by police compared to 1,130 blacks. In that respect, Medved is correct.
However, Brian Forst, a professor in the Department of Justice, Law and Criminology at American University, said this difference is predictable.
"More whites are killed by the police than blacks primarily because whites outnumber blacks in the general population by more than five to one," Forst said. The country is about 63 percent white and 12 percent black.
Rather than comparing the raw numbers, you can look at the likelihood that a person will die due to "legal intervention" in the same way you might look at the chance a person will die in a car accident or a disease like lung cancer. When you do that, the numbers flip.
A 2002 study in the American Journal of Public Health found that the death rate due to legal intervention was more than three times higher for blacks than for whites in the period from 1988 to 1997.
