On Dec.2 Knucklehead linked this seemingly dispositive piece which convincingly asserted Corps of Engineers design flaws (or contractor chicanery) as the cause for the failure of the flood walls in NO. There was even a clever bit about the LSU investigative team: The corps has long claimed the sheet piling was driven to 17.5 feet deep, but Team Louisiana recently used sophisticated ground sonar to prove it was only 10 feet deep.
Today another piece appears (HT Skookumchuk) which refutes through actual physical evidence the core of the previous piece. Maybe.
Sadder (but in all probability no wiser) I believe that I will withold further speculative comment until a definitive report is published. There are too many axes being ground by both sides at the moment to have much confidence in the reporting.
