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.

And then there is the fact that illegal immigrants do not call the police for their fears.
3 people "screened and analyzed" 1.1 million calls and found out that there was a (presumably temporary) effect on minorities after one much-discussed incident involving minorities? The rest is cherry-picked examples and wild conjecture and not thorough analysis of the data.

Um, that's because they're illegal and has nothing to do with racism.
