Kimmage is just another old "has-been" with too much time on his hands and you know what they say about "he who protests loudest" - makes me wonder if he himself has something to hide and somehow trying to exonorate himself by attacking others.
Sad bitter twisted old man in my opinion!
I may be wrong but that suggests you don't know much about him, particularly about his book, Rough Ride, a seminal piece of cycling literature. One thing we can say is that he doesn't have much to hide. The only thing we haven't seen is his intestines.
Apologies if I've misinterpreted your post.
