With reports of a runaway barge that may have crashed through the Industrial Canal, an LSU expert who rejects the theory  that "overtopping" breached the 17th Street levee, and even rumors of explosions -- and now the documents from 1990s court proceedings suggesting structural weaknesses -- we may never know definitively what caused any of the floodwall failures, let alone all of them.

Nevertheless, I come here for solid, original (and scientific) analysis, so I'd be interested in any insights about what happened.

It's not an analogous comparision, because here the evidence is incontrovertible -- but while we're at it, why don't we debate whether WTC was a controlled demolition, or whether a plane really hit the Pentagon?

Is this post serious? Really. To me it borders on comedy. For my own knowledge, let me know. I'm curious.
Actually it was.
Maybe it was a set up, maybe some important people turned their heads the other way. I'd even go so far to say that the arguments above are more convincing than the arguments against (once you take out the societal inertia component in the balancing of the various theories). But since most folks are unwilling to even consider such things, why discuss them when we could be finding ways (through drawing in other disciples/areas of interest like detailed NOLA analysis) to get people really concerned about PO and its interaction with the looming ecological catastrophe.
