In this Abstract piece, James gave a very detailed account, with supporting evidence and documentation, of why Jackson was guilty. The thing about the triples was one of the reasons.
Personally, I think Joe Jackson probably should get a break after all these years ... especially if they let Rose back in. I've always figured that Joe Jackson, who had the intelligence of a retarded amoeba, got taken advantage of in a lot of ways, although bottom line one must take responsibility for his actions.
I just don't think it's accurate to say that he did nothing to throw that series, and if I can find which issue of the Abstract that piece by James is in I'll at least cite the year, there's no way I'm going to type in a three-page article.
