You just made think about how in depth the show took each character. No matter how minor or large the role. The effects of government, gangs, etc on a city. Perfect quote from the creator. Simon has said that despite its framing as a crime drama, the show is "really about the American city, and about how we live together. It's about how institutions have an effect on individuals. Whether one is a cop, a longshoreman, a drug dealer, a politician, a judge or a lawyer, all are ultimately compromised and must contend with whatever institution to which they are committed."
