In arguing for adding some $13.7 billion in penalties to costs already incurred by BP following the April 2010 Deepwater Horizon explosion and Gulf oil spill, federal lawyers displayed images of fouled beaches and dead, oil-coated birds in a New Orleans courtroom on Tuesday, Jan. 20, 2015. BP points to $42 billion in costs it already has incurred in arguing for a lower penalty. (AP Photo/Dave Martin, File)
