MARY BURTON
Thank you very much.  I am sorry to have made you condense a very comprehensive testimony into a short time, we really appreciate it very much.
 I would like to ask one question.  I don't know whether any of my colleagues may want to ask questions too.  You mentioned seeing people you refer to as "witdoeke", for instance in the Zwolani Centre incident.  How do you identify those people, I mean were they known to you or do you identify them some way as being "witdoeke?"
