Natonwide: Arrests by Population Groups: Whites 69% Blacks 28%
Nationwide: Population by Groups Whites 78% Blacks 13%
As per the 2013 reports from the FBI and Census Bureau .... and the arrests do not include any traffic offenses, which were included in the DOJ investigation of Ferguson.
Compare the national figures to Ferguson:
Ferguson Population Black 67%*
Ferguson Arrests Black 93%
*There was no data in the report to distinguish between Black people from Ferguson vs. Black people from outside of Ferguson who were being arrested. It was reported in the news that Ferguson is surrounded by areas that have a higher % of Blacks than Ferguson, in which case it would more than likely increase the Black traffic into and through Ferguson, thereby increasing police contacts with those outsiders. (Many of the protestors were reported not Ferguson residents, as an example.)
It is obvious from the Report that a statistical "bias" can be shown, but to carry that to the level of calling the department "racist" is not supported by the report or the stats.
When nationally 2x's the Black population are arrested for non-traffic offenses, but in
Ferguson "only" 50% above the population % are arrested out of the total arrests, WHICH INCLUDES TRAFFIC.
The real point is that Wilson was exonerated of any racial motivation in his response to Brown by a finding there was no evidence to support such an allegation against him. That's what got this Ferguson Race accusation going .. and the "hands up" protests. It was Wilson being accused of shooting Brown because Brown was Black. There is no evidence of that ... by the DOJ,, Holder, the Grand Jury, and the DA.
