And what we largely determined is that there seems to be a lot of idiosyncrasy with respect to police hiring.”

“Law enforcement agencies have to appeal to people’s sense of duty and civic participation by getting out into the community and insisting that the goals of the Police Department are to represent the city and serve the city – and that includes every aspect of the city,” McCrary said. “Every neighborhood, every block, every citizen.”
