When in doubt, put it to the t-test.
Interesting that the death sentence is available to secular authorities, and the Church has a complex process for determining if the accused is a witch.But there is no mention of weighing the woman in a scale containing a duck. Nor of any townspeople being turned into a newt.
I thought not having a contingency plan for if your victims got better was also an oversight. Maybe this was only validated for American witchcraftery, not British.
