Fially, I think the producers should chose their "experts" a little more carefully. Many of the people interviewed in this production have some serious skeletons in their closets, whether it be working for the wrong people, having your qualifications questioned or revoked, taking money from special interest to build a case, or just plain doing faulty work. Here's some links to those in the production that I found intersting.
