A couple of commenters rightly pointed out that I failed to provide the url for the IG's report that I referenced earlier. My error: I did not have the url when I wrote the post, and forgot to go back and add it later.
I would also encourage those interested in the topic to read Jay Fitzgerald's series of articles on Tourism Massachusetts, some 10 or 12 of which ran in the Boston Herald between December 2006 and February 2007, when the IG's investigation began. To the best that I can tell, the IG's report refutes nothing in his articles. Unfortunately, the Herald charges for archived articles, so I don't have url's to give you.
