more mistakes

The White House got detailed warnings about the likely impacts of Hurricane Katrina:

The NISAC analysis accurately predicted the collapse of floodwalls along New Orleans's Lake Pontchartrain shoreline.

The documents shed new light on the extent on the administration's foreknowledge about Katrina's potential for unleashing epic destruction. President Bush, in a televised interview three days after Katrina hit, suggested that the scale of the flooding in New Orleans was unexpected.

Perhaps somebody could tell me when all of these mistakes cross the line between simple incompetence and blatant criminal disregard?
