I've been wondering if we might think about how the jury might have organised their deliberations.
Imagine you are the foreperson and it's day 1 of jury retirement, and you have to all agree the way in which you will structure the discussion of these cases.
Even though the prosecution mixed it up a little bit in their closing speech, and provided lists of patterns to consider, would you follow the same approach? I think it could quickly get messy, if they decide to use patterns as their order of deliberation, because then you are jumping in at random points of the year, if say you are looking at the cases where the prosecution say she attacked when parents had just left, you then miss the context of the evolution of change of alleged methods, say her beginning to allegedly falsify babies' notes to say doctors had examined when they hadn't and babies had started to deteriorate when they hadn't, and texting friends to say the babies were poorly on handover etc.
I think the starting point makes a difference to how deliberations would evolve. The insulin poisonings could, if the jury decided she was guilty of them, provide a springboard from which they would accept the mindset of malice aforethought, which you wouldn't have if you started at A. Even if you started at A, your mind would still be conscious of what laid ahead, but would you decide that you should put the blinkers on and not consider that until you got to it? And then would you discuss F and L together and interrupt the sequence, or still plough through in date order?
I think they might have collectively agreed to start at A and work in order, which might also have been at the expense of using the alleged patterns, at least initially. It would avoid the messiness of jumping forwards and backwards, and people having different ideas about what for them was their strongest case. It might not be the best way of deliberating but it avoids what might be perceived as personal biases and less time spent deliberating how to deliberate, rather than actually deliberating the cases.
