The red (the northwestern three-quarters of Louisiana) are the parishes that were declared subject to the emergency powers before Hurricane Katrina made landfall. The green ones (southeastern portion, including all of New Orleans) were not.
I blogged on this topic earlier, citing an article that showed that Louisiana police (from Gretna, Jefferson Parish) not only prevented refugees from leaving New Orleans, but stole their food and water.
Someone really needs to overthrow the corrupt, incompetent and dangerous government of the failed state that is the USA.
