For someone to be accused of a crime, the person accusing them had to have proof.
This woman has been doing witchcraft, I have proof!
No I haven't! What do you mean?
If you were accused for witchcraft, you were immediately dragged to the nearest body of water.
I promise you I am not a witch, I haven't done anything.
You are then stripped down to our undergarments and bound with rope.
You were then thrown into the water to see if you floated or sunk.
If you floated you were guilty and would be pulled out of the water and burnt at the stake, but if you sunk you were innocent, you were quickly pulled out of the water by the rope attached to your waist.
Quick pull her out she's innocent.
But if you were innocent and sunk, you often didn't make it back alive.
There were also crimes for lying, which means, if you falsely accused someone you were punished.
Oh no, she died, she wasn't a witch and she died, oh no, oh no, oh no.
Wait, you said you had evidence that she was a witch, but she wasn't so you lied.
