Read this ChicagoBreakingNews article about a Black couple who filed a complaint against homeowners who said outright that they "preferred" not to sell their home to a Black. I can't believe this still occurs today, but we see it will make the news.
Newsalert makes a connection between this Bridgeport couple and the Chicago mob and Chicago Democratic machine.
Also note we're talking about Bridgeport historically this neighborhood has been hostile towards blacks. In fact the 1919 race riots had their principals between both Bridgeport and the Black Metropolis.
