by Greg Bowens Detroiter Ed Black looks up at the billboard with a new sense of hope. High above the Golden Greek Bar, at the corner of Marx and 8 Mile, a billboard went up around 1 p.m. Monday afternoon. “Racial profiling zone? This is it! This is the zone,” says Black.Facing east, it blares a warning for westbound drivers: “DANGER Racial Profiling Zone. Cameras Out! Share Your Story 313.883.9121.” The billboard towers above the intersection at 8 Mile and Dequindre – where the borders of Detroit, Warren and Hazel Park meet. This sign is for Hazel Park in particular but all the suburbs adjoining Detroit in general. It’s the third and newest such warning along the city s northern border, erected by the Racial Profiling Across 8 Mile Committee – a loose confederacy of 10 activists in Detroit and the surrounding suburbs.
