When I was small my dad had to do jury service in the village of Dolgellau in North Wales. The last case on the Friday was a small time poacher who everyone on the jury knew and who they all knew was almost certainly guilty.
The judge informed the jury that if he was found guilty then they would have to all return the next day, Saturday, for sentencing (we are talking 45 years ago here).
Dad was refereeing a school rugby match the next day, someone else had a hairdressers appointment etc etc.
Funnily enough the decision was “not guilty”.
If you don’t want the jury service to go on longer than necessary…
