Cameron wants Bill Bratton because he believes England has a race problem , then why not say so ?
The televised police beating of a black suspected car thief last week will test two years of efforts by LAPD Chief William J. Bratton to win over the city's African Americans.
But it also strikes at Bratton's deeper and more ambitious agenda: fixing America's race problem by fixing its crime problem.
Putting his theories on race relations into practice is one of the reasons he came to the Los Angeles Police Department, Bratton said. He sees race and crime as "two seemingly intractable problems in American society, inextricably linked."
