How about 'Across 110th Street?' I always thought this was a very underrated movie. They used to have it up on Youtube but this is worth watching for the opening sequence and Bobby Womack's title track alone:- http://www.youtube.com/watch?v=JxCsIX6iU5o

'So I say, “Live and let live.” That’s my motto. “Live and let live.” Anyone who can’t go along with that, take him outside and shoot the motherfucker. It’s a simple philosophy, but it’s always worked in our family.'
