It is beginning to look as if this Raila has bit off more than can handled: Internal civilian violent dissent, even if expressed through tribal loyalities: foreign neighbours admitting he (Ugandian President Yoweri Museveni) has never been particularly fond of Raila and there were discussions before the elections about the implications of a Raila win.
I have no idea what the presence Ugandian troops means - but I hope a discpilined force will be able to stop the killing.
