Thought people might enjoy this read - I heard discussion of this on the Michael Brown Show (on 630 KHOW out of Denver). The article was submitted by a listener - while I have not checked the facts (there are a lot listed), however it is an interesting read.

You may remember the name Michael Brown - he was the FEMA director during Katrina, although that has no bearing on the article, it was not written by him, only discussed on his radio show.
