Here is a link to the report.
If you have no bias, or a bias anywhere left of the Grand Dragon of the KKK, and read this report you should be outraged. The Ferguson PD systematically targeted blacks and violated their Constitutional rights with impunity. If the Ferguson PD targeted gun owners the way they did blacks and subjected them to similar abuses this board would be crashed with the rage posts. Instead we get a collective, meh. Either you believe in the protections the Constitution affords every citizen, unilaterally, or you do not. There is no middle ground.
I haven't read the full report and it may be some time before I do, but aren't you assuming there is "no bias" on the part of the report creators?
FWIW, I have little doubt that there was systemic abuse and bias in the Ferguson PD. They certainly haven't done anything to disabuse anyone of that notion since the shooting. But if you believe Holder when he said DoJ had no pre-conceived notions upon entering Ferguson, I have a bridge to sell you.
