Stockades

How exactly do the stockades work? I went to the judge with evidence and requested judgment. He took 500 silver but the criminal did not show up in the stockades for me to whip or throw tomatoes at.
Also I tracked a claim on evidence an the pointer pointed at the ocean when tracking in providence. Is their an island out in the ocean?
