It was a clash of the mayors.
Mayor Michael Bloomberg and former Mayor Ed Koch disagreed with each other at a panel discussion Tuesday when asked about their response to the Occupy Wall Street protests.
Bloomberg says the banks are being wrongly blamed for the mortgage crisis when Congress was at fault.
Koch notes that major banks have been fined millions of dollars. He says that's because they "abused their relationship with their clientele.''
Koch says he wants an executive of a major corporation punished criminally.
He says: "There's something wrong with a kid who steals a bike going to jail, and someone who steals millions paying a fine.''
Bloomberg also revealed a softer side. He says the criticism he receives hurts, but he doesn't show it.
