If you are not familiar with Mau Mau, I highly suggest you become so.
Robert Ruark wrote two novels about it, based on his time in Kenya and friendships with Kenyan farmers and hunters.
Very gruesome, but it gives great insight not seen in 'historical' accounts.
The first book, "Something of Value", covers Mau Mau & the lead-up to it. The second, "Uhuru", centers on the post Mau Mau period, and the politics involved.
Viewing O with an eye on his origins, and his acknowledgement of them, provides an insight never covered in the press.
The Mau Maus were mostly Kikuyu but a few of Obama’s Luo tribe were involved, including his grandfather who was imprisoned by the Brits and came out psychologically broken. Barack Sr was really too young to be involved but he surely believed in the Mau Mau aims.
