MR PRINSLOO
The element of surprise is always the overruling element at  that stage.  It is like people entering a bank, they know that there are tellers, they know that there are guards, but it often happens that there is a shooting, that the police were informed from outside and that they would start shooting, and so you cannot mutually eliminate any of these elements.
	He knew the place, he knew there were guards, there was a small room, why would he suddenly expect six guards, why would it be different, he knew the Air Force.  He went and reconnoitred the other place.  He was aware of the place there in Pretoria where there were normally two guards, but that day there were six.
