It was very difficult to vouch to that, but I would say that what criteria we used at the time was on which side of the two strongholds a person resided, and if a person resided on the opposition's side we would conclude that he supported the opposition.  For example there were many people who were killed on our side, but later on it transpired that they were not members of the ANC, they only got killed because they resided in the area that belonged to the ANC.
