Common man, you are smarter than this and know that this is media hyped hysteria. The police kill people indescrimantly. And the prision system is rigged yes but against the poor not by race.
It's also worth noting that every time a cop gets off scott free for killing in the line of duty, the message is sent to everyone else in the community that the police are driving around your neighborhood as an act of intimidation, since you never know if saying the wrong thing or making the wrong movement will get you killed. Police forces are out there to protect property first, and wealthier property owners second. In any poor community, a police force is an expensive, burdensome army of occupation...no different than the paramilitaries that frequently harass residents of favelas in Brazil and other high crime Latin American cities!
In a nation like the US of A, it's sort of a moot point to say that the criminal 'justice' system is rigged against the poor, when color tracks so closely with poverty! Although white poverty is growing rapidly in the past 10 years.
