Ok breh. You're right. The prosecution doesn't have the right to cross-examine the author of the evidence the defense presents.
The defense has all the right to cross examine the evidence/authors of evidence of the prosecution. But not opposite.
Got cha.
Breh, IF they even play this video, it's author is the forensics guy. You would have a point if the video was made by GZ and a graphic artist, but thats not the case.
It was made by a forensics expert based on his investigation of the facts of the crime scene.
obviously, since its the defense's witness he probably collaborated with GZ at some point in the making of it, but thats not how it will be presented to the jury.
