Berg did not go to London, Jerome Corsi was there but I have no knowledge that he looked into colonial Kenyan records.
You are right, it was Corsi instead of Berg. I heard an interview with Corsi from London saying he was going to be there a few days doing some research. Isn't Corsi working with Berg, doing the research or coordinating? Do I have that confused also? There are so many cases and so much non-info info that it gets confusing at times.
