A new Pew poll confirms the not-terribly-surprising fact that there is a huge racial gap in the public's perception of events in Ferguson. This is seen across a variety of questions they asked, but the two most important are these:
Most White Americans have confidence in the integrity of the investigation into Michael Brown's shooting, black Americans do not. Concurrently, most black Americans feel the police have gone too far in cracking down on protestors, while whites seem divided and somewhat apathetic about the issue.
Separately, we have some evidence that white people become more supportive of the criminal justice system when they are made aware of racial disparities.
