Fear and Loathing in Zimbabwe

Apparently the African Union has declined to intervene in Zimbabwe. I'm going to admit that I have no clue what's going on down there, but I keep hearing and reading snipets about this guy Mugabe. I'm under the impression that there's more going on here than just evicting poor people from their homes.

If anyone (anachronism? Billy D?) has any clue what the rest of the story is, please feel free to give me a link or something, because I'm pretty sure that I don't have the full score on the situation.
