The DNO should have prevented this from happening, hence the value of the penalties.
The runner may have well seen it and just thought that he could throw it out of his way when he was running, why note.
At that level is should have been safe, however, it seems it was not, so the DNO was criminally negligent as has been found by the court.
Nothing can bring the innocent runner back to life.
I don't think it would have been that large, and why should he have realised that it was not insulated.
This is a catalogue of errors from the DNO which put the general public at risk, this should not be happening in the name of profit, which is what is occurring.
The DNO's should be maintaining their network with safety and reliability above shareholder profit, however, this is not the case and it is a disgusting abuse of the UK users, for profit to be channeled into private companies, which, should be criminal and this judgement is a good start.
