"They don't care about us" version I never saw till today

In Michael Jackson history album, I always felt the strong message in the songs about social problem of the world. I only get to see the original release version of the MTV which was him singing in Rio de Janeiro but never did I know there was a prison version.

After watching the following video, I really felt that is how MJ really want the video to be. I can feel the emotion of the songs.

One for Michael.
