Getting critical care patients out in short order is extremely difficult. Heck, all levels of government didn't get anybody out who could not drive out on their own. It was a massive failure from top to bottom, and all deserve blame. Never again.
What I find appauling is that there was no provision for a non mandatory evacuation prior to the mandatory one. Why couldn't buses have been provided beginning 48 hours before the projected land fall for anyone wanting to leave but with no private means of transportation. I think the mayor should have at least had the authority to declare a volunary evacuation and started using the school and transit system buses. Both the city and state had a plan to use transports that they owned to evacuate vulnerable areas. Why didn't they execute those plans.
