On most weeknights, in the middle of his shift, Los Angeles police officer Keith Mott trades his gun and uniform for a T-shirt and shorts, and heads to a park in the Watts neighborhood of South Los Angeles. He's there to coach 7- and 8-year-old boys on the Pop Warner Pee Wee football team, the Watts Bears.
The kids come from three nearby housing projects: Jordan Downs, Nickerson Gardens and Imperial Courts. The park was carefully chosen. It's a neutral site for local gangs. Otherwise, most of the Bears' parents wouldn't allow them to come and play.
Since the 1930s, Louisiana has lost roughly as much land as makes up the state of Delaware.
"If you put the state of Delaware between New Orleans and the ocean, we wouldn't need any levees at all," says John Barry, vice president of the Southeast Louisiana Flood Protection Authority-East. "There is this large buffer of land that has disappeared, and that buffer makes New Orleans much more vulnerable to hurricanes."
