Isn't the only person who can confirm that kind of dead?
you don’t have ears?? or just that you have LIBERAL ears where you only hear libtard speech...
No, the rule of evidence can confirm statements. As an example, FDR stated; "a day that shall live in infamy.." - the rules of evidence can confirm that.
The officers who were there probably could, if any could be made to testify. They could even use the video to refresh their recollection.
But this witness certainly can't. The lawyer is asking a retained expert witness for his lay opinion on what he can hear in a video that is already in evidence. If the prosecution objected to that question, I think the judge would have to sustain it: the witness is in no better position and is no more qualified than the jurors to determine what is being said on the video. The video is already in evidence, and the lawyer is certainly free to argue to the jury in closing what he thinks Floyd is saying.
