You hit the nail on the head when you admit your ignorance about the history of CKGR and that of Botswana in general. Of course our tribal land was converted in to Bushmen Reserve in 1961. Period. The name later changed to CKGR. Botswana gained independence in 1966. The government of the newly independent Botswana did not decide to relocate us from CKGR until 1985.
I am sure you are able to calculate that this was 19 years after independence. President Ketumile Masire appointed a Fact Finding Mission (which I refer to as Faults Finding Mission in a book due to be published in the near future) in 1985. Based on the findings and recommendations by this Mission, the government decided to relocate us from CKGR. I am sorry, but you should not tear your clothes and get wild if your ignorance is exposed by the most downtrodden of society.
