Patsi i disagree with your definition of what Murphy's law is.
"Murphy's law is a popular adage in Western culture, which broadly states that things will go wrong in any given situation. It is most commonly formulated as "if anything can go wrong, it will." The law was named after Edward A. Murphy, Jr., a development engineer working for a brief time on rocket sled experiments done by the United States Air Force in 1949."
I would say in this case everything and anything that could go wrong DID go wrong. Poor communication, poor idea on who lived where and how many and if they got out. Bad communication about where the hurricane could possibly go thuse FEMA and other resources got wiped out with new Orleans. Upper level people totally unsure who to ask for help, and if they "should" ask for help from the military and if the President would even allow it. Storm shiffted course. Levies failed.
Strewn liberally through out this whole thing is a rampant use of stupidity as well. People staying to party, the mayor not knowing how many people live in his city. not sending in FREE transportation to get people out. People shooting at rescue helicopters and hi jacking trucks loaded with medical supplies. President not reacting sooner and calling off people that were ready to help.
