You guys should write up real laws if you do that caging or stockades and make some of them obscure (well more obscure than stealing) like loitering around the road, walking through town with weapons drawn, or sitting on the grass in some towns just to show the difference in the realm's towns. So a desert town would probably have laws against spoiling water and death for poisoning wells.
A fun law would be, "no climbing tress." That would teach them elves.
Anyhow, think it would be interesting.
