i think American international policy and Ferguson issues are two different things.
Surely America needs to revise it's international policy but things that happened in Ferguson needs to be seen from the point of view of cop who happened to be "white" and the person who died happened to be "black" with questionable background.
From what i see in modern day America, whites have relaxed a bit on racism whereas blacks are still cashing out the suppression issues but not all blacks are doing it.Those who moved forward from 60s mentality are doing very good.
If this is about "innocent" person getting killed at the hands of a cop then probably there are 100s of other cases that needs international media attention.
If this is about white killing black issue then statistically blacks are killings blacks more than whites killing black.Everyday in big cities number of people die because of gang violence and most of them goes unnoticed.
i was reading this other blog yesterday where it listed out number of innocent white people getting killed by a black person.
