Quite contrary to BD's claim that JB's night time cycle ride wasn't possible, we have RB's assertion that such is exactly what happened. Who would have known best? A townie who was only there for holidays, or a life long countryman?
RB didn't like Jeremy. Whether that be justified or not. He didn't.
I'm not going to say " fit him up" but it's obviously from the outset he was trying to change the police directive. I'd wager from the first moment they saw him at bourtree they believed he had done it. This is before the silencer discovery.
How much knowledge did RB have of people on the sea wall at night, I'm guessing the same as BD, Difference is RB had an interest in Jeremy getting convicted. He wasn't exactly neutral.
How far was RBs farm? Am I right it was called carbonells?
