Actually, what I was interested in was *when* Berg was in Kenya. Your source shows him to have only gone there in 2003. That contradicts what I was told about him being there in 1998 (when our embassy there was bombed).
Your source, however, is more credible. I was likely misinformed. This works in NB's favor, making it more likely that he was simply naive and kind-hearted and strangely in a lot of coincidental places.
