At the end of "Rogue Warrior", he said that he was imprisoned for counts of conspiracy, and something about funding, as mentioned before. I'm assuming that he did a lot of the writing in prison, which is probably why some of the parts are so negative.
But isn't the guy like 60 some years old? And I'm pretty sure he's made too much noise to still be in the Navy. But I still want to buy his Red Cell video, just to see the authenticity of some of the exercises, which seemed pretty intense in the book.
