It is good that supporters and guilters can be flexible and agree on possibilities. And agree Julie may have been telling the truth.
In this instance both agreeing the twins could have been shot first.
However I don't agree there is any evidence showing this definately happened, which supporters recently claimed. No one knows the order of the deaths.
I also don't believe if there ever is evidence the twins were shot first, it means Sheila was the killer, as also recently claimed by supporters. This thread has given several reasons why Bamber would and could have shot the twins first, (once each).
A scenario to match the crime scene has also been created on this thread showing how Bamber would successfully committ the massacre after shooting the twins first. Which is in contrast to posters recently not being able to explain what Neville was doing when Sheila started shooting the twins. Partly because people did not want discard the 'Neville phoned Chelmsford police' card.
