Or Sheila could have painted her nails earlier in the day. Then become docile later on.
Bamber's reconnaissance & PB's phone call were only around 4 hours before the massacre.
But you've told me the prosecution case doesn't depend on Sheila being docile, so why engage in all this elaborate guesswork about circumstances you were not witness to? She did this, she could have done that, Jeremy did this, Jeremy believed that, Sheila never did this. How do you and Steve know all this? Were you there?
You don't know when she did her nails or that she was sedated or docile. Neither do I. I merely ask how it can be that she could do her nails at all, ever, if she lacked basic motor co-ordination. Did she just take her time? Steve says she was dishevelled by habit. Then why was she found clean? Did she get herself ready specially for Jeremy, knowing he was coming?
I think you dogmatic pro-guilt people need to get yourselves in a gridiron huddle and sort your story out. You seem to be in a bit of muddle at the moment, changing what you say depending on the objections raised.
