Similarities between the Hurricane Katrina tragedy and the BP oil spill are, distressingly, many. One of the most striking echoes are the two men ostensibly in charge of the disasters, Michael Brown and Tony Hayward. In a fit of pique last weekend, I drew a little something about the two executives and their glazed, disassociated stares. In the coming weeks, I hope to check in with some of A.D.’s subjects to get their sense of things five years down the road from Katrina and eight weeks down the road from BP.
