Here's the problem. There are social issues in America that need to be addressed but the Michael Brown case is not the place to try to address them. Neither was the Trayvin Martin case.
But politicians like the status quo. They have no incentive to change unless they are about to be outvoted.
The 1% in control of the Gov't like the status quo (other than they want to pay even less taxes). They have no incentive to change unless they are about to be taxed more.
America's "issues" won't change until someone in power is about to lose their job or a shitload of money. If there is enough "social unrest" the media will keep the pot stirred until the economy or the safety of community will maybe force some change.
America's law enforcement has ZERO accountability to anyone. A barber or a manicurist has stricter state regulation and accountability. Cops are in charge of the oversight on cops. That needs to be changed. It will never change until it is a big enough issue to affect the re-election of the incumbents or economy of the rich.
