Liddy wasn't in a foreign prison with 90 local inmates in his cell. Going up to the biggest guy in the room and beating the hell out of him would not have done this dude a bit of good. He still would have been passed around. I have a feeling there is a different class of filth in an African prison.
You are probably correct on all counts. However, I do remember Liddy describing seeing another (the only other, as I recall) white prisoner receiving similar treatment in his prison to that described in this article.
