It strikes me that there won't be much practical good to come out of this trial.
True
The professional investigation already evaluated the evidence and took what action was deemed appropriate to restore safety
The trial is to satisfy the public's need for blame and punishment under their laws, much like our executions do.
So let the trial proceed towards that end in order to satisfy the law of the land and we can revisit whether the punshment fits the crime after it is handed down. Else all we might do is whine about a law that we neither created nor live under
