Having been through the experience of having a family member involved in a serious RTC that they were not expected to survive, I can say that it strikes me as perfectly reasonable that the victim's account of the prosecution doesn't make sense, that there is something missing, something odd.
My family's experience was awful and we desperately wanted to know what had happened that night. Later, we wanted to know why the criminal case had evaporated (also involving a failure to stop). Our solicitor wanted to know why the police were particularly evasive and obstructive, more so than in any case in her twenty years of specialising in RTC resulting in serious brain injury.
But when you have to fight every inch of the way for a settlement in a civil claim against the driver's insurers, a claim that the Police threaten to withdraw any assistance from if you pursue a complaint, your need to get on with life as best you can starts to outweigh the need for answers (not that any contribution the Police had made could be considered assistance - despite closing the road for several hours as part of a fatal accident investigation the only paperwork that generated was apparently a hand scrawled sheet of A5 - the threat was that to that stage they hadn't yet chosen to be 'difficult').
The civil claim against the insurers was settled after six years for a six figure sum - the only interim payment that had been made was a paltry amount to cover the immediate expenses of the events of the evening. The fact that I contributed over ten thousand pounds for time critical maxio-facial/dental work (through their specialist) was actually used by the insurers to justify that sufficient support existed without the need for interim payments. Everything is a battle, eventually you'll most likely just want to walk away from it all and the insurers use that to beat you down.
When our solicitor said that now that the civil claim was settled she was prepared to pursue the Police for the inadequacies of their investigation we declined.
She wasn't ambulance chasing, she had been appalled by their behaviour. Their actions had severely compromised the level of compensation awarded and she believed that they should be made accountable. The evidence she had accrued was insurmountable and she believed compensation in the order of multiples of the insurance payout was in order. We had no more fight left, not even for millions. In fact, during the midst of this I was deliberately hit by a driver while cycling and suffered a shattered collarbone requiring two operations. I had video of the incident but couldn't face even more of the same trauma that was overwhelming the entire family, I didn't pursue a claim.
I mention all this not just as a rant (and I know I go on about it) but to point out that the system is stacked massively against non-motorised RTC victims - police, courts, insurance industry, even public opinion (making an appeal for information results in some very unpleasant responses). It's hard enough when the processes of justice and restitution run 'smoothly'. If someone within the system goes about making things difficult it is horrendous. It's also pretty opaque.
I still have no idea what exactly led to the experiences my family had in dealing with the courts and police being so difficult. Ingrained bias? Corruption? Cover up? I can't discern where the problem arose but I know that deliberate actions obstructed justice, I'm just not equipped with the resources to accurately point a finger or if I did, deal with the consequences of doing so.
I also have a fair amount of experience as a witness of matters being pursued through the magistrates' courts.
Justice at this level is not a well resourced principle. Competence in prosecution and defence is hugely variable for various reasons. Legal argument generally isn't as robust and incisive as drama and reportage might lead one to expect.
In one case I was involved with, a driver was aquitted of assault but found guilty of a driving offence. The evidence objectively showed him punching me in the head but driving in accordance with the specific traffic regulation that he was convicted of breaking - it was the right result though. The punch was rubbish but so was his general standard of driving and it was his driving that posed the greater danger.
Basically, if anyone is dissatisfied that the cyclist hasn't provided the complete picture, there may not be a great deal he can do about that in this specific case. All he might be able to manage at this point is show that this happened, no one was held accountable and that that is wrong.
Once justice has supposedly been seen to be done a victim is limited in the accusations they can continue to make, both legally and in avoiding compromising recovery and compensation. All we can do is look at the bigger picture and question how our society allows this to happen.
