For all the emotion, and as a London rider who'd hate to be in the same position I put in to the fund, that we have here, I think what
@Pale Rider is doing here is clinically looking at what has been published about the case and explaining (from a position of some knowledge) why the decision has been made. And while I don't like it, it is kind of compelling. I hate the idea that a driver on Regents St has killed a cyclist and it appears nothing is being done about it. Unfortunately, the legal system we have, as has been shown multiple times in this thread, has been used and come to a conclusion. The conclusion is horrible, but based on what the options are it looks like the case has nowhere to go. While the gut reaction is, this should be pushed and pushed it looks like a court wouldn't prosecute, without more evidence. What is obviously wrong to the majority of people posting on this thread isn't enough.
We don't know if she came up behind him while he was riding straight and true and just drove through him, similarly we have no idea if he had a lapse of concentration and moved for the bit of road he needed without any kind of observation. Both could be true and that's all that matters without evidence to prove which it was.
Again, I think we've been given the answer. This case has faltered because of the requirement to prove, in law, things that the evidence can't prove. If the law was changed to 'Causing Death by Driving' with no requirement to prove, based on the legal definitions, careless or dangerous driving then this, and other cases would get to the next stage and have their day in court. Maybe that's where the focus needs to be?
Although the emphasis used, when the statements were made and how they were released, especially the retraction. Those were undoubtedly a travesty.
