And everyone in the place just sits quietly and stares at their shoes, ... that's america. We can blame the cops all we like - and we should - but they only do what an entirely gutless, impotent, colonized and subjugated people spinelessly allow. We've been totally desensitized to this in society. It’s in our faces and we do nothing.

Dylann Roof and Travis Reinking get taken into custody with kid gloves, and this is what happens to black/brown folk, and to a lesser extent poor whites. Let's all just face it, black, brown, poor bodies feed the for profit prison industry and whites are to ignorant and indoctrinated to understand this stuff is for them as well in a post-industrial society where the substantial people no longer require the work force they once did to generate profits.
