That's not even true. Mayor Nagin ordered a mandatory evacuation a 9 am the morning after the federal government declared a state of emergency. You're so ignorant of basic facts - and appear to be willing to just make shit up when you don't know - is it worth even debating you over it?The Federal Government ask Nagin to evacuate New Orleans. He and the Governor refused. In fact the day before the Hurricane Nagin was still refusing to evacuate.
