Here is what this appeal will come down to:
1) Defense witnesses re: tampered files, expert classification.
The reason the appeals judges pestered the
State about this is because there is precedent. I expect the appeals court to rule that Gessner erred in disallowing JW (and GM in that) to testify in this capacity. He did allow an airport cop looking at his 3rd computer to testify in this regard for the State
2) Would the purported tampering testimony (disallowed) have affected the verdict?
Of course, it would have. The jurors said as much. To compound this, Boz insisted in the State's closing argument that (paraphrasing here) "not one witness from the defense testified that these files were tampered with". Dumb...because this reinforces the concept that "untampered" map files were crucial to the State's case. If Boz had not said that, I'd give this appeal a 50/50 chance at a new trial. As its stands i would be surprised if THIS appeals court (based on past rulings) does NOT grant BC a new trial due to Gessner's error in not allowing testimony.
I don't think the FBI issue with "national security" will even need to come into play.
my prediction:
*State emphasis in closing i.e. "no defense witness told you there was tampering"
*Gessner (in error) disallowing above testimony
=reversal, new trial and Gessner has Boz, in part, to thank for that.
BC guilty or not, it is what it is.
