When I look at this picture I don't think 'that must be what liberty is' I ask myself 'how could a government allow someone to live like that?' The idea of liberty is freedom from oppression mainly from a place of authority, that authority could be the bus driver who picks you up, to your employer or predominantly the government. This image is iconic because when you think of an American ghetto you don't think of a middle aged white male, you think of a young black male as seen in this picture, ask yourself why that is and for me it's because you know there is still oppression and racism in America no matter how much they try to deny it which completely negates the idea of liberty.
