"Silky" Bob's profession shows that he was a cheap man that wanted money and expensive stuff for free but Jimmy Wells understood that money came from hard work and he wanted to stop the ones that thought it came for free. When he came to realize his best friend was one of those he couldn't arrest him because it was his friend. Jimmy was a hard working American while bob was feeding of of people like Jimmy and taking their hard earned money from them for his personal use. That's what i believe from that story.
