MR VISSER
Basically, in the beginning, due to my experience from the police, I did a lot of information gathering.   Fortunately at that stage I still had a lot of my ex-informers from the Security Police days who advised us on certain information that we needed on the African National Congress, the South African Communist Party, so our information that we got from them were then evaluated, sifted and then tested, and then if necessary we passed it on to the correct persons in the structure.
