I looked at what I could google up. One document even came from you. The mass of Kenyan documents I've seen use the British dating scheme. Some of the documents using the American system actually were US documents relating to Kenyans, not Kenyan documents. Some were obvious fakes. One might have been legitimate, but it was not representative, and you couldn't build a case on it. If you want to produce the documents you posted earlier, we could discuss them, but that's up to you.
Yes, it was in 2009 that Lucas Smith obtained the document from Kenya.
That would be the Lucas Smith who swore he paid over $5000 in bribes to get the certificate and then tried to sell it on line? For that money, he could have gotten George Washington's Kenyan birth certificate. And of course, it's not an official birth certificate. It's something that could easily have been concocted for the kind of money Lucas was throwing around in a poor country.
