The crux of the W.C. position on the fragments, that CABL (composition analysis of bullet lead) proves one shooter based on results tying the fragments together and to the Manlicher Carcano, is debunked in this chapter.
Here is the final paragraph of the chapter's conclusion:
(P.163) CABL can neither confirm nor refute the single bullet theory. In fact, in 2005 the FBI denounced comparative bullet led analysis. Therefore, scientific testing of ballistic evidence in the Kennedy assassination does not support the Warren Commission in their conclusion that Oswald was the only shooter in Dealey Plaza.

I know Sherry is very busy this week with the conference in Dallas and will inevitably weigh in but, until then, the search function can be used to find some replies she has made as well as other discussions we may have had on related subjects.
