I'm not suggesting anything.
The testimony was that this was a cover sheet. The date/time and some other details of the incident don't change - that's why they are the same.
Over time these reports are updated. I would assume with additional interviews, details, evidence, photos... whatever. All of that information is contained within the report - presumably with dates and times of the updates.
The defense was keying on the photo on the cover sheet... implying it was some kind of effort to make it look like that photo was taken on the morning of the incident vs. being added later.
This, of course, is silly. Any information about that photo would be contained in the ACTUAL report. Why did the photo on the cover sheet change? What would this even accomplish (if it's yet another part of the big conspiracy)?
The officer who was questioned didn't know... it didn't seem like a manual process he was familiar with (ie. he or anyone was dropping and dragging photos to create a report) and he suggested it might even be the software just grabbing the last photo added to the report or similar.
OF COURSE - this would be all be very easy to verify, if the defense actually cared to.
