I am sure that DI Mason recorded many more facts than are listed in section B of the report they produced after the complaint against him. However, the text that I have quoted appears in a bullet point list headed "the areas which supported his rationale and that he conveyed to DI MASON". Explain to me again why he would have listed it as supporting his rationale not to take the case to the CPS if he didn't regard it as relevant to his decision not to take the case to the CPS, because even your helpful double-spaced one-sentence paragraphs don't seem to make your argument less self-contradictory
Strictly, this is what DS Edwards said he outlined to DI Mason:
Mr MASON (Deceased) was wearing dark clothing, the collision having taken place during hours of darkness.
An independent witness at the scene (Neil TREVITHICK) stated that with the sea of brake lights, flashing lights and movement it would be difficult for a driver to pick out anything.
CCTV traced corroborated how busy the area in general was, with both motorists and pedestrians.
All witnesses traced could not describe in any detail the lead up to the collision.
Mr MASON was not wearing a cycle helmet, the cause of death being head injury.
CCTV recovered from 2 independent venues highlighted that Ms PURCELL’S vehicle was travelling at an appropriate speed. This is corroborated by the minor damage caused to the vehicle after impact.
CCTV showed Mr MASON cycling between 1.5 to 2 metres from the kerb line. No CCTV exists depicting Mr MASON moving from his line of travel, i.e. moving out to his right. This is something he must have done in order for the collision to have taken place.
CCTV, physical evidence and Ms PURCELL’S own account prove that she had always maintained her position in the road, adjacent to the central white line.
We were unable to show the point at which Mr MASON moved over to his right. All we could conclude was that during a distance of 25 to 30 metres, Mr MASON at some point changed his position in the road.
Within that is the fact cyclist Mason was not wearing a helmet.
DI Mason listened to what his sergeant told him - a lot more than the above summary - took into account whatever other evidence he had, then decided it was a 'tragic accident'.
As I said, you will have to ask DI Mason what relevance - if any - he put on any individual fact or piece of evidence, only a tiny proportion of which we have here, summarised, third hand.
