All this week, we are looking back at the events that triggered the financial meltdown, one year ago. Today, we focus on the housing market, then and now. We talk to economist Robert Shiller, of the Case-Shiller home-price index, who was among the few experts to warn of the coming housing crisis. We also speak to New York State Supreme Court Judge Arthur Schack, who has a penchant for halting the bank foreclosures that come before his bench. (Read his profile in the New York Times, "A ?Little Judge' Who Rejects Foreclosures, Brooklyn Style") And we also talk to Pamela Zombeck, who is struggling to hold on to her home in Salem, Massachusetts.
