What red marks? While I agree this is probably a fake, I still don’t see the red marks. The only red I see is on the edges but that’s most likley due to compression of the doc with a white doc and red background blending.
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.
