MS VAN DER WALT
When you say movements, you say that he knew your movements as well as some of the other members, by movements do you mean that which you were working with at that point, the type of investigation you were doing at that point because you trusted him to gather certain information for you?  For instance he was told to investigate let us say, person A, is that what you mean with movements, the types of investigations that you did he was familiar with those and that if he came out as a double-agent, that he would have transferred that information to the enemy?
