MR MALAN
I wonder as a person whose first language is Afrikaans, I understood him to say: "When I made my statement I had to make as full a disclosure as possible.  The risk involved is that one may put in things that then turn out not to have been so because you to rely on your memory".  So "chance" might as well have been a synonym in this instance for risk taking.  I hope that helps you because I didn't see anything - but you may pursue if you want to, I didn't see anything intended to go beyond stating the obvious there.
