How does your world deal with magical crimes?
This is something that's fast become more prevalent in fantasy as the years have gone on, but I'd argue that the crimes, laws, and punishments are usually pretty basic; either have your magic removed a la gentling from The Wheel Of Time and the Right Of Tranquility from Dragon Age or just straight up killing the offender. Usually, this applies to those who use magic to cause physical harm, but what about when an alchemist turns lead into gold as part of money laundering? What if an enchanter provides dodgy goods? What if a healer commits a medical error? Unless your justice system is binary, they can't all be gelded or executed.
With that in mind, how do you approach magical crimes in your setting(s)?
