The Estate can indeed not be involved, but it doesn't mean that they weren't fooled. And the same goes for the experts.
I already added that
and then you are left with two possible results
- as they passed a legitimate evaluation they are really authentic - they are Michael.
- they were able to fool a legitimate evaluation - therefore there's no way to prove it's not Michael.
Either possibility doesn't look that good for doubters.
The Estate is however responsible for their strategy. As I said, Branca is maybe a very good businessman, but without Michael he's short sighted to such an extent that he couldn't predict how much these songs would harm some fans,... well a big number of fans. He just opted to go by what experts say. Furthermore, if he really wanted to make some kind of damage control, he'd better release some details regarding the analyses. There's no reason to keep them secret, unless he is hiding something from the public.
I think people moved on , including Jacksons from this issue. this is one of the few threads and you are the only few that is still remaining focused on this issue.
edited to add: You may not agree with their strategy - well even I don't agree with it to some extent but I think they have a consistent silence or 1 statement / silence approach in all matters. They did the same thing in this instance as well , even asked Teddy to stop talking. Right or wrong, I think that was their decision and they would stick to it.
