One doesn't have to go back that far to find evidence that police in Ferguson, Missouri treat blacks differently than whites. Blacks are about 3 times more likely to be stopped and about 5 times as likely to be arrested than whites.
First, I do fine with statistical evidence. I used knowledge already seen to make my analysis, without reading your cited numbers, but lurking in that article is a likely explanation for the discrepancy in traffic stops.
Whites were more likely to be found with contraband. If you were carrying contraband (usually drugs) wouldn't you drive more carefully? Raw numbers rarely tell the whole story. For example when the Boston Fed found evidence of discrimination based on numbers of blacks turned down for mortgages, it wasn't discovered until later that the rates of foreclosure were nearly identical, showing that rather than discrimination, the underwriting standards were right about the risks.
Presuming discrimination due to more tickets and stops presumes that both groups are driving the same, or it could mean that blacks drive more recklessly, and disregard the law and safety. Both conclusions from raw numbers could be wrong.
