I’m looking at the “disparity index” for Ferguson, and I notice that the Hispanic index number is little different from the white number, and sometimes lower.

Going to the 2012 page for the link, 2012 data, I see that the “contraband hit rate” is 17.6 for black stops and 16.0 for white stops. That’s a disparity but a weak one and these kinds of numbers have some static in them so it doesn’t indicate much.

I also looked at the ratio of citation vs warning. Those proportions were pretty much the same for whites and blacks.

The “outstanding warrant” ratio was greater than the stop ratio, which says that traffic stops for blacks were more likely to be a stop of someone who had an outstanding warrant.

If stops of whites yielded more outstanding warrants than stops of blacks, per stop, that would indicate that the police were going easy on whites.
