Here's some real data: https://www.bjs.gov/content/pub/pdf/rpa11.pdf
Across all races and Hispanic origin, American Indians and Alaska Natives (15%) and persons of two or more races (15%) had the highest rates of reporting crime or neighborhood disturbances to the police. No statistical difference was observed between the percentage of white (9%) and black (7%) persons reporting a crime or neighborhood disturbance to police in 2011.
Also, perhaps I'm reading it wrong, but Appendix Table 4 suggests that minorities are much more satisfied with police response than the average.
