This 1964 photo shows fear personified. An unknown photographer captured two black teenage girls running away from a mob of white policemen in the middle of a Brooklyn riot. The picture shows the often excessive wielding of power by certain factions of the law, and is particularly poignant given continued police brutality in the US and the struggles of the Black Lives Matter movement. The image was later used in The Roots’ critically acclaimed album Things Fall Apartreleased in 1999.
