ANSWER
"Occupants of an ANC house in Gaberone", I think uppermost in my mind was the names of Joyce and Rola Dibali, but except as I say always that anyone present in the house could be armed, the house was used for ANC purposes and you can be shot if you start identifying targets it takes a long time, specific persons in the house and to separate them from other people in the house, you could end up dead because the house was used for ANC activities.
