For years, Iraq's oil infrastructure — its pipelines and refineries-- has been a regular target of the armed insurgency.
Attackers detonated bombs in one refinery in February, and explosions breached the pipeline carrying oil from northern Iraq to Turkey in March.
In response, Iraq has created a police force with the special mission of protecting oil and gas facilities. The center for training the Iraqi oil police is known as Camp Dublin: It's a small corner of the American and Iraqi bases around Baghdad's airport.
Talks at the White House on Wednesday night did not produce a budget agreement, and a government shutdown is still looming. President Obama, Democratic Senate Majority Leader Harry Reid and Republican House Speaker John Boehner left the meeting saying they will continue to work toward a settlement.

Fifty years ago this May, 13 people boarded a bus in Washington, D.C. The Freedom Riders, as they are called, challenged segregation on buses and in waiting rooms throughout the South. Some of those riders are using their experiences to motivate students today — to show them that the actions of one person can make a difference.

"There's Dave Dennis," she says, "looking up at the guys with the bayonets."
