I've sat through the not-guilty verdict that let George Zimmerman walk free, I've sat through the Michael Brown and Eric Garner grand juries that let murdering cops walk free, And they are just a few of hundreds, maybe thousands.
This is how you radicalize elements of society. This is how you create "terrorists." Right now, every black and Hispanic American with half a lick of sense knows as a certainty that, unless they are rich and/or celebrities, they have no expectation whatsoever of being treated with any degree of fairness or equality by the American "justice" system. They can and will be murdered with impunity -- man, woman, and child alike -- with no expectation of justice being done to the murderer. If they commit a crime, or are suspected of doing so, or are merely going about their lawful business, they can and will be arrested, brutalized, manhandled and slaughtered. If they survive the process, they will be incarcerated in a for-profit system for years and decades, forced labor for a post-millennial slave owning class.
The poorer they are, the fewer resources they have, the more likely they are to say "Fuck the system" and start preparing to take justice into their own hands, mob justice, vigilante justice, you name it. Racism, hatred, bigotry, white privilege and fear are not "going to" ruin American society. They have already done so. We will reap the whirlwind. Blood has been spilled in small, painful amounts; expect a cataract in our very near future.
It is not a matter of what I do or do not condone, or what I do or do not support. It is a fact, just as global warming and the depredations of fracking are facts. On a societal level, the consequences will be just as catastrophic. I do not condone or encourage violence. It doesn't matter what I condone or what I want. The white racists have destroyed American justice. They have poured the gasoline and set the fire, and they need not cry out in horror and fear as the flames begin to burn.
