Oh, I doubt that those retaining walls were constructed under the Bush administration, although I don't know for sure.
But facts are facts. Either the floodwalls failed, or they didn't (they did).
And either they were properly constructed, or they weren't.
As the Gipper famously said, "facts are stupid things."
Yea, they were hit with a Cat4-Cat5... Only designed for Cat3... How can you sue them for that? What if they were designed for a Cat5 and they were hit by a Cat6?
