Oh, please. I don't have time to go hunting links to satisfy your curiosity. This is from bits and pieces garnered over several years following much of the debate about the COE's supposed failures since Katrina, and was frequently TV snippets.
I'll ask ONE question of you instead. Exactly why is it, that the means and structures designed, built, and maintained by the COE over the entire rest of the the Mississippi valley (and many other places...including the rest of Louisiana) work just fine, with the only significant failure happening in the immediate New Orleans area??
Thanks for admitting you have no documentation for your false claims.
Your question is a good one. It is the kind of question that would be answered in a trial with full discovery, etc. What is the name of your family friend, the Army engineer? If he was involved in building those canal walls, we should be putting him on trial for criminal negligence and manslaughter. Then we can get your question answered!
