This is an interesting brief that I saw yesterday. Its a good summary of what the Federal response to Katrina. All this info is available in open source, but this is a good roll-up. This info is 24 hours old, but still pretty good.
Hopefully, I won't irritate my FEMA brothers by posting this, but I don't think they'll mind a little good press.
So here is some death by powerpoint, FEMA style. Enjoy.
