Personally, yes I do, but I understand how difficult it was to produce (Roux's is full of holes and statements of 'fact' which are merely supposition) and have also seen others of a legal bent state that it was not necessary. That said, Masipa seems to have thought it was in her Judgment because she remarks on the absence of it.
For a long time I thought the issue was Johnson's phone time (and it may well still be), indeed Johnson did too. I no longer do, other than to state as a fact that if his phone did show a call at 03:16 then it could have been at any time between 03:16:00 and 03:16:59 because of the truncated seconds. For a bat then gun scenario (see my early two posts on page 18) the issue becomes the Burger/Johnson sequence of events, which I argue is incorrect. If this is accepted, everything falls into place (it requires that the shots they hear are moved to before the helps). I have produced a simple schematic to help me visualise all the witness testimony based on this which I will post soon as a picture and then supply a link to the document at a later time with a full explanation, relevant witness testimony etc.
I am surprised that any evidence, such as phone calls, is put into court without appearing to have been properly investigated. Phone records cannot be difficult to obtain.
