TESTIMONY_GIVER:
  As I said, Mr Chairman, I could detect nothing from him looking at him as a person.  I could see nothing funny, but apparently his behaviour became peculiar in some way.  I didn't ask specific details about it, but he was able to walk, he was friendly when Nick van Rensburg greeted him in single quarters that day, and when he got out of the car at Komatipoort he was walking on his own.  He looked quite normal to me.
