Well I guess JB was relying on the officers to make notes and not for him to keep reminding them of what he ( alone ) saw when lights were going on and off. What officers saw and what they wrote down were two entirely different things once it came to trial----such as the figure in the window which changed to a trick of the light. I don't see it being JB's problem at all. It's not his fault if police chose to miss out what they all saw that night.
We weren't talking about lights, we were talking about whether there were one or two phone calls to the police. West and Bonnet did write down what happened, it's just that West wrote down the time of the call wrongly.
Nobody saw lights going on and off. The police wrote down what they saw - it was up to the jury as to whether to place any credence on it. Clearly, the jury didn't believe that anyone was alive in the house when the police got there.
