Whether Sheila was fully fit or very docile, Bamber was confident enough to go ahead.
He had spent long enough planning everything & only had a short window of opportunity before Sheila left.
The WS's of Bamber, PB & Julie, together with the crime scene evidence suggests the Haloperiodal had made Sheila very docile on that night.
To be clear, are you telling us that, in your view, the prosecution case does not depend on Sheila being sedated?
I have not seen a witness statement that tells me Sheila was docile. Pamela Boutflour tells us that Sheila wasn't very talkative, but that could be for any one of a number of reasons. Sheila could have been angry and sulky at that point.
Could you bring this all together and tell us what the precise argument for the prosecution is on this point?
It seems to me there are three main possibilities:
Is it that Sheila's illicit drug use and drinking increased the sedative effect of her Haloperidol, with the consequence that when Jeremy woke her and seized her, she was utterly relaxed and pliant ('docile' is your term)?
Or are you asserting that Haloperidol was the primary sedative agent, and since she still had a lowish dose of it in her, this was enough to make her sleepy, therefore it was utterly impossible for her to embark on a massacre, while quite easy for Jeremy to manipulate her into a staged suicide pose?
Or are you disregarding the sedation argument altogether and telling us that, irrespective of the drug's sedative effects, Sheila was asleep anyway. Jeremy grabs hold of her, etc., or maybe she wakes and goes into the main bedroom before Jeremy gets there, or any variation on that theme.
