The Justice Department's Public Integrity Section has a storied 34-year history of pursuing corruption in government and safeguarding the public trust.

That trust was breached, however, when some of the unit's prosecutors failed to turn over evidence favorable to the defense in their high-profile criminal trial of Sen. Ted Stevens, R-Alaska, who died earlier this month in a plane crash.

Now Jack Smith, a 41-year-old prosecutor with a love for courtroom work and an impressive record, has been brought in to restore the elite unit's credibility.

Before Stevens, Public Integrity's renown was built on large successes — like the prosecution of the Jack Abramoff lobbying scandal and convictions of federal and state judges, members of Congress and state legislators, military officers, federal lawmen and bureaucrats and their state counterparts over the years.

But its stumble — not disclosing exculpatory evidence as Supreme Court precedent requires — was equally large. It was so serious that Attorney General Eric Holder, one of Public Integrity's distinguished alums, stepped in and asked a federal judge to throw out Stevens' convictions.

The revelation that BP's Texas City refinery emitted toxic benzene for more than a month has ignited a furor in the port community that has suffered its share of deadly industrial accidents and toxic spills.

Thousands of residents who fear they may have been exposed to the known carcinogen released at the oil refinery from April 6 to May 16 have been flooding parking lots and conference halls where local trial attorneys hosted information sessions and sought clients for class-action lawsuits against the oil giant.

BP faces the new challenge just as it is reaching a key milestone in another crisis — plugging the Gulf of Mexico well that blew out in an oil spill disaster that is costing the company billions of dollars.

On Wednesday, more than 3,400 people lined the hallways and sidewalks around the Nessler Center to sign on to a $10 billion class-action lawsuit filed Tuesday in Galveston federal court by Friendswood attorney Anthony Buzbee.

The lawsuit alleges the release of 500,000 pounds of chemicals - including 17,000 pounds of benzene - has jeopardized the health and property values of people who live and work in the area. At the nearby College of the Mainland, a separate town hall meeting drew a crowd of 600.
