We can never know how the conversation went, because there is no record of it; however, there's no other way RS would have brought up this. He would have had to have been asked directly about this knife and about MK's DNA on it, not blood, DNA.
Logically, an RS would have said he had no clue. So he would have had to have been pressed to offer more.
What's completely ignored by the other side is that Mig taped other "witness" statements, even ones made in his office. It is unacceptable that the primary witnesses' statements were not recorded. FR's was recorded. Why not AK or RS's? Mig admitted to this in the CNN transcript.
So again, I do not know why we are debating it, because the other side has already conceded that if the court says it, it's true. And the court ruled the statements inadmissable in the murder trial. So why are they now contesting the basis of that court decision just because people on AK's side have repeated it?
