Witches or sorcerers and burning at the stake or witch's stool/dunking

[Joe Coffee]

I hope there's an outcome of jobless peasants who become bandits or cutthroats may turn to becoming witches and performing dark arts and curses in your province.

Then if you can catch them in the act, if you can sentence the offenders to burning or drowning.

...

Yes, I'm aware of the Monty Python skit, but I'm serious here. :)
