At the time the WH released the BC, part of my job was using photoshop to combining elements of multiple photos into a single photo (for completely legal purposes). I worked down at the pixel level (image blown up to 3200%). Individual pixels of the photo are 1/2" squares on the screen. I know the necessary techniques to hide traces of editing. Cut and paste is easy to identify at that magnification unless action is taken to blend at the pixel level.
The WH released BC was a very sloppy job. I knew within 10 minutes that it was a forgery.
There is no benefit to beating that dead horse now. Nothing is gained by creating a constitutional crisis. However, I will correct anyone who arrogantly claims the BC was not a fake.
Truth is always worth the effort.
Thank you.
