Dow plunges to lowest level since 2004.

Wall Street joined a “selloff around the world” today, with the Dow Jones dropping more than 400 points and falling to below 10,000 for the first time in four years. As the AP reports, the “markets have come to the sobering realization that the Bush administration’s $700 billion rescue plan won’t work quickly to unfreeze the credit markets, and that many banks are still having difficulty gaining access to cash.”
