Perhaps the response was not good, I've heard varying reports and don't trust most of them, as it seems to depend on one's politics. I fail to see, however, how the federal government could be held responsible for people to ignore repeated warnings and choose to sit in below-sea-level homes for days before a storm actually hits, then drowning as a result. You could have rolled a wheelchair out of the danger area. Simply walking over to the French quarter would have done the trick. I wasn't aware all the dead were quadraplegics or blind people with no phones, relatives, or ability to summon a ride out of the area.
And at some point you have to ask, why are they criticizing the government that is four levels up, but not the state, parish, or city governments? The answer that comes to mind is political bias.
This sort of chauvanistic bias is why we can't solve problems. "Them = evil/incompetent , Us = perfect". For this reason, this type of comment is not to be taken seriously.
