One comment I saw on CNN was, "Racism is like oxogen, it is all around us". Regardless of the details of the death, that will eventualky become public, racism seems to be an underlying factor in the citizens response.

As to the government response, I suspect because of the muliple jurisdictions, it does not seem to be well designed to quell the local and broader public concern that meaningful justice will be done by a unbiased agency. If this were done early, police could focus on isolating troublmakers versus mixing them in with concerned citizens. There are genuine questions about who is in control and whether they have the skills or interest in dealing with the bigger picture.
