Is there agreement from everyone that Sheila did not shoot herself downstairs in the kitchen. Then walk upstairs into the bedroom without any of the raid team seeing her. Then shoot herself again.
The court pathologist said it was impossible.
Going by what the entry team reported on entering that there were 2 bodies, then a further 3 found upstairs, it's most likely they saw Nevill and Sheila downstairs.
It was is possible she moved, as the the first shot was non-fatal.
This is why the tapes and documents need to be released - in full, NOT edited.
