No, it is not. There was no plan to get those without transportation out. Even tourists got trapped.
The argument as to the government's responsibility to provide transporation is not absolute.
Government bears a responsibility to make sure that everyone in a city like New Orleans can get out if there is a disaster. The city failed in that regard. Grossly.
I disagree. This is not a fact, it is your opinion, which you have every right to hold. On this our opinions of governmental responsibility differ, and with that we will have to agree to disagree.
Stay safe.
