It would appear as if Scorpion was arrested in early 1980 and was then recruited as an informer.  It is strange to me, if these letters are correct, where long allegations are made by Oupa Madondo about having been assaulted, letters from 30.08.1979, then it could definitely not be Scorpion because Scorpion was only recruited early in 1980 and killed in the middle of that year.
