Video and pictures of crime scene
It is possible that the police made a video of the crime scene as presented. My informant told me they did a reconstruction? I have not mentioned this before but often pondered what he meant by this since you need bodies etc. to accomplish this and all participants in the event would need to repeat their actions in a timed exercise.
What I think he means is that the TFG used a video or a series of crime scene pictures as an aide memoire to instil in their minds the scene that they were supposedly presented with on entry for the purposes of statement drafting and the like. They could fabricate their narrative to present a co-ordinated and realistic view. The recollections of things being a little different from what they remembered were, in my opinion, all ‘gilding the lily’ to add authenticity to their lies.
Since they were all given immunity, interviewed under PII rules, they could do this knowing it would not rebound on them.
Alternatively, he could have been referring to a reconstruction of the crime scene, which could have been better described as a restaging.
