I have neither seen the documentary nor have I commented on the documentary.
I have merely stated that in my experience the NO District of the COE was the least corrupt agency with which I had dealings in SE Louisiana whether Federal, State, or Local. Given that a significant part of my business involved planning, executing, and negotiating dredging contracts, levee construction and repair contracts, canal restoration contracts, and pump station maintenance and construction contracts (valued at a guess in the $100s of millions) involving not only the COE but also local and state agencies responsible for flood protection I am comfortable that my experience provides a not unreasonable basis for arriving at an opinion on the subject.
I further stated that the fact that Orleans, Jefferson, St. Bernard, and Plaquemines Parishes were at risk if a hurricane of 3 or better came up the Mississippi or through the Rigolets was not arcane knowledge; in fact it was common knowledge - hence the pervasive fear of another Betsy.
Finally, I noted that Katrina was not a worst case scenario, that, in fact, a far worse disaster would be the failure of the river levees at flood. That event would be a catastrophe of truly epic proportion.
Lest I be accused of being calloused in my view of the effects of Katrina I should tell you that my mother, her brother, and his wife, were amongst those who elected to not evacuate prior to the storm hitting. I flew into Dallas and drove to NO in the immediate aftermath of the storm to evacuate them. I brought them out through Dallas. My aunt and uncle lost their home and everything they had in it; it was not insured. They have never returned. My mother's home sustained significant damage that took months to repair.
