If you read through all 1800 posts (so far) you’ll find that the guy who made the image with the red marks confessed to his deeds. He was merely trying to “clean up” the image.
So the issue remains: we’ve seen a photograph of a document that is claimed to be the original Kenyan birth certificate of Barack Obama. That document has apparently been submitted to a court which hopefully will take matters seriously and will authenticate the document in the photograph.
So is the image with the red marks different than the image in the initial post? If so that explains it..it not I still don’t see red marks on this image.
