"Michael Rushford of the Crime and Consequences blog calls attention to a new study by John Lott, Jr. of the Crime Prevention Research Center and Carlisle Moody of the College of William and Mary. The two scholars developed a database for police shootings nationwide from 2013 through 2015. Their database is significantly larger and more detailed than the data available through the FBI.
Lott and Carlisle found that white officers are significantly less likely than black officers to kill black suspects (see page 14). They also found no evidence that body cameras affect either the number of police killings or the racial composition of those killings."
