We're not arguing over the existence of God here. Sure, you can never truly prove a negative, but you can never truly prove a positive either. New evidence leading to exoneration (above and beyond a mere finding of "not guilty") is still a coherent and useful concept to anyone who isn't philosophizing their way up their own ass.

There could have been something like DNA evidence eventually showing a different perpetrator, or proof that he was in a different country when the alleged incidents occurred. The sort of thing that would make it instantly clear to any reasonable observer that the recovered memories did not reflect reality. I was primed to expect an eventual finding like that, but there wasn't one.
