@Bikesandbees - the CPS have seen all the relevant evidence, which will include the woman's medical records as they pertain to this - so they will have seen that she had no previous record of seizures and that she has since been diagnosed with epilepsy. These are the facts, and if the CPS - who are the experts in what will and will not constitute a crime - think that the facts prove that this was a horrible and unavoidable accident, with no criminal liability, then what is achieved by taking it to court?
If it did go to court, the CPS would present the evidence, and the defence would present the same evidence because it is exculpatory - it proves her innocence - and that would be the end of it.
But for that to happen, you would have to assemble the prosecution and defence lawyers, the witnesses, the experts, the doctors, the jury and all the other court staff - and all for nothing. And the costs of this would come out of the public purse.
In the meantime, cases with strong evidence of deliberate criminal acts would get bumped down the list, and victims would wait longer for justice. Even if you only did this for cases where there was public outrage, you would still end up crippling the justice system, and that would benefit no-one except the real criminals.
Can you explain what this woman could have done to prevent herself having an entirely unforeseen seizure whilst driving? Because if you can prevent seizures in people who don't know they are about to develop epilepsy, then the medical community will be beating a path to your door!
Some things are just horrible, tragic accidents - not everything is someone's fault. Dh and I had a tyre blow out on the motorway a while back. Luckily we were able to get onto the hard shoulder without causing any problems for anyone else, but it could have been very different - that blowout could have caused an accident where people could have been hurt. We maintain the car well, and before a long journey, dh always checks the tyre pressure and the tread depth - he checks these regularly anyway, and tends to be more conservative than the guidelines, so replaces tyres that are still legal and safe enough, rather than take a risk - but we still had a blowout. It was not foreseeable that a tyre in good condition would blow out - and if anything bad had happened, it would have been an accident, not our fault.
This case is the same. She didn't know she was going to have a seizure and lose control of her car - so what happened was an awful, tragic accident.
