The General Social Survey asked people how warmly they feel toward blacks. Answers ranged from "very warm" (scored as a 1) to "very cool" (scored as a 9) so we're really measuring coolness. Participants were also asked about their current occupation (sample size = 2,729). Here are the means by race and occupation:
Mean "coolness toward blacks" score
White police officers 3.67
White civilians 3.67
Black civilians 2.12
Other non-white civilians 3.69
White police officers do not differ from other whites in having a mean score which indicates quite a bit of warmth for blacks.
Now, you might point out the blacks have a warmer average, but all racial groups tend to feel warmer toward themselves than other groups do. Significantly, police officers feel just as much warmth for blacks as Hispanics/Asians/etc do. So, whites and non-whites who are screaming at the police for their racism, officers are the same as your group: They feel favorably toward blacks.
