This is true, and to the extent that the justice system is supposed to provide a deterrent effect and a reinforcement of cultural norms, the fact that the verdict has not been (or cannot be?) explained as reasonable is itself an indictment of the system. What are we supposed to learn from this incident? "s*** happens"?
Well, sh'it does happen. That is one of the first lessons in life. But I don't think it's the lesson that was planned in this case.
Had the verdict been inexplicable or unable to be explained as reasonable, then the judge would have made reference to that and that is the story the media would have picked up. The media love a story like that, so we may be able to assume that he didn't. If the judge didn't find the verdict inexplicable, perhaps it wasn't.
The justice system is (as you rightly say) supposed to provide a deterrent effect. But in this case the jury decided that in terms of the charges brought no crime had been committed, so there is no need for any deterrent. A judge will not and cannot say "You've been found Not Guilty, but I need to establish a deterrent here, so you're going down."
Similarly, the Not Guilty verdict suggests that cultural norms have not been exceeded, even though that judgement or assessment is not really the place of the Crown Court.
I believe that anyone wanting to obtain a copy of the transcript of the trial would be able to do so. Until they have it, they have (as we have) only press reporting to go on. By its nature this will be incomplete, little more than a veneer. In-depth reporting is reserved for cases involving Cabinet Ministers and Hamstead Heath.
The verdict in this case is one with which many CC members do not agree. As far as I am aware, none of the CC members is in possession of all the evidence put before the jury. On that basis, this is not an indictment of the system. It seems if anything to be further proof that the system functions; it just doesn't function as we may want it to.
The angry villagers are not
meant to burn down Frankenstein's Castle. The suspected rustler is not
meant to be lynched. The courts are there to allow justice to function, not to put it in the hands of people who read something in a newspaper and wrongly predicted the outcome.
I find the verdict uncomfortable and wrong-headed on the basis of all that I've read, but it is not an indictment of the system.
