UNKNOWN
Again, I would like to answer you question actually as two answers.
 My perspective is that there was interference and that there was some sort of scull (indistinct) taking place.  However, I do not have the evidence to substantiate that.
 And I work with evidence, I work with facts.  I do not believe in the colour grey. I like things to be either black or white, but as a South African citizen as hopefully a thinking person, there are questions that I cannot answer and that makes that I draw certain perceptions, not dissimilar possibly to what you are putting to me.
