It isn't just George W Bush.  The damage was spread across the Gulf coast.  In God's eyes, sin of omission, law it is dereliction of duty and/or negligence.  It was all over the news.  They KNEW it was bound to be bad. 

The mayor of New Orleans.  Governors of Louisiana, Texas and Mississippi, etc. the zones where the thing was forecast to hit.  People in Us congress, what do we have law makers/decision makers for?  I got in an argument with Sue Williams, my sister in law, that they could have sent in the military.  She said it would have been dangerous.  The military is trained to be brave, which is why we have the thing in the 1st place, to serve and protect those who cannot do it themselves..

Hurricane Katrina was an extremely powerful and catastrophic tropical cyclone that killed 1,392 people and caused damage estimated at $125 billion, particularly in and around the city of New Orleans, in late August 2005. It is tied with Hurricane Harvey as being the costliest tropical cyclone in the Atlantic basin. Katrina was the twelfth tropical cyclone, the fifth hurricane, the third major hurricane, and the second Category 5 hurricane of the 2005 Atlantic hurricane season. It was also the fourth-most intense Atlantic hurricane to make landfall in the contiguous United States, as measured by barometric pressure.

Katrina formed on August 23, 2005, with the merger of a tropical wave and the remnants of a tropical depression. After briefly strengthening to a tropical storm over south Florida, Katrina entered the Gulf of Mexico on August 26 and rapidly intensified to a Category 5 hurricane before weakening to a Category 3 at its landfall on August 29 near Buras-Triumph, Louisiana.
