I was definitely thinking a good rifle in .308, but after all the comments about Katrina I am sort of not sure. Maybe big bore revolver like .357 or .44 for concealment and power.

I am also very curious about what guns were confiscated during Katrina.

I am under the mindset that everyone on this forum would not allow themselves to be put in the position that the citizens of Katrina were put it. Everyone here seems to want to be prepared and are educating themselves with survival/gun knowledge, experience, and law. If something like Katrina happened here (any natural disaster) I am thinking that no one on this forum is going to stick around.
