Warning spoiler following if you haven't seen the show. If you don't watch it but want to know why I'd bring it up then keep reading.

The key piece of evidence in the murder case is a chop! They even showed how the elements were put together from externals. Impressive chop too if it was real.

So, for those that saw the show, do you think that was really a chop? Or did they stage all the photos?

No" I was busy watching CS2.

I watched part of it, and saw the part with the chop.
I bet it was chopped, they probably staged images with similar backgrounds for the show and selected them and adjusted them before filming. But I bet it was chopped.

I did think it was rather funny how the image forensics guy literally grabbed parts of each photo and dragged those (fully visible) into another image and they transformed in perspective and lighting while moving to the new image.

My wife thought chopping was easy before. If she ever saw that she'd really think I was off the rocker about how tough it can be.
