You need to watch a video, because you have just made the best case possible for why the line up identifications can not be trusted. The odds of this happening are indeed astronomical!
Martin has harped on this being only a "circumstantial" evidence case apparently misunderstanding that this term doesn't mean weak. He now informs us that direct evidence can't be trusted either. That really narrows things down! We are finally getting to the center of the lollipop, though. At its heart what John and Martin are contending is that nothing can ever be proven if they don't like the implications. The case against Oswald is the collective product of lies, fakery, unfairness, coincidence, police incompetence, chance, being unlucky, but never Oswald's guilt.
