FILE – In this July 23, 1967 file photo, hundreds of people run down 12th Street on Detroit’s westside throwing stones and bottles at storefronts. The riot started after police raided an after-hours club in a predominantly African-American neighborhood. The raid, though, was just the spark. Many in the community blamed frustrations blacks felt toward the mostly white police, and city policies that pushed families into aging and over-crowded neighborhoods. (AP Photo/File)
