A white policeman facing a group of afro-americans. Detroit was 85% white in the 1950s until the 1967 riots generally called the 1967 rebellion by the black community. 50 years later, Detroit's population is 85% afro-American after the "white flight" towards the suburbs. Because of the gangs, it is also ranked the most dangerous city in America. At the same time, the USA are regularly facing the problem of the murder of afro-americans by white cops, what led to the "Black Lives Matter" movement. I was on the first floor of a building when i saw this "encouter".
