MR VAN VUUREN
I can only explain by saying that it becamemore and more difficult to get informants.  It was initially veryeasy but it became more and more difficult.  As the people's warwas continuing it became more and more difficult.  People fearedfor their lives and  they were scared because if it was foundout that they were informants, they were necklaced the followingday and their families were killed.  It became more difficultto get informants.
