What I would say is this, in fact Caiphus was never a leader as a Cosas member.   He was just a member.   So there was a fear because Cosas was of the view then that black local authority was used as a tool to oppress the black communities.
 So, it was something which we as blacks were not supposed to support, because it was something imposed on us by the white Government.  Then again it fought educational issues, like those of age limit, if you remember, because when there was this threat that if a child of a certain age, doing a lower standard that child should not be allowed at school.  So that was an issue that Cosas did not want.  They said everybody has the right to attend school, to be given that right irrespective of their age.
 And there were issues against such as those of corporal punishment.   Those were educational issued that Cosas were involved in.  
 So, I think the local Councillors then were threatened by those views of Cosas.
