For a man with a mural of an oil refinery in his office, deciding to sue the oil and gas industry wasn't an easy choice.
But it was a necessary one for Guy McInnis, the president of Louisiana's St. Bernard Parish, just south of New Orleans.
On a recent day, McInnis stands overlooking Lake Borgne. Now an open lake, the area was once prime wetlands and marshlands that protected St. Bernard from storm surge. It took a big hit during Hurricane Katrina.
Oil companies would dig through the marshy area to get to their shallow water wells.
