By Max Holland. Good book. I know the author. He's coming out with another on the Warren Commission itself.
"Having read this book I am sure of one thing - which is that LBJ wanted the Warren Commission to be a blue ribbon rubber stamp of the lone nut theory."
You have to keep in mind that the case was pretty conclusively solved within days of it happening. By the time LBJ formed the Warren Commission it was already clear that Oswald did the shooting. He wasn't as focused on solving the case because it was already solved. What he wanted to do was avoid the circus of having multiple investigations and congressional hearing all going on over the same case. That was his state of mind.
The Commission was tasked with finding the truth, including any conspiracy that might have happened.
