I don't see anyone questioning the amount of the federal response except you. How fast do you think YOU could mobilize . The President declared an emergency BEFORE the hurricane. There is a massive mobilization of National Guard going on, and in case you forgot, in order to get those troops there from points north they need GASOLINE and CLEARED ROADS.
I didn't question the entire fed response, in fact I just praised most of it as massive and amazing. It is the apparent lack of a sufficient military presence to maintain order that I question. But I should add the lack of communication to the masses wandering the area, too.
Of course the mayor and gov have dropped the ball, this is where the Pres steps in. If they weren't grant authority, publicize that, and the refusal would immediately back down. If you don't think people are questioning why there aren't more troops in there, perhaps its town to go down to the grocery store or coffeeshop and listen to the conversations. Until the rescue operations resume full-scale, those questions will increase.
