Similarly, a lot of police work in modern America is persuading black witnesses to show up to testify against black criminals.
Strangely, though, nobody has ever produced much evidence that diversity hiring improves policing. In the largest such natural experiment, Congress ordered Mayor Marion Barry’s Washington D.C. to hire 1,800 additional police officers in 1989–90. By all accounts, this proved a disaster. As of 1994, over 100 of D.C.’s new cops had themselves been arrested.
