Now you've heard the evidence that  one of the factors that aroused the suspicion of the Security Branch that the people who were going to infiltrate South Africa from Botswana, that those people were in fact South Africans and not illegal immigrants and probably members of Umkhonto weSizwe, was because some or one or more used a Black language when speaking to your informer, a Black South African language, I should imagine when speaking to your informer, did you hear that evidence?
