MODERATORS
They do know how it works: it detected a pattern in the difference between fingers and checks that.
Also this would usually not be needed explained to a jury. If they have the suspect in custody they can just check their fingerprints directly.
That's again 2 fingerprints to compare: one from the crime scene, and one from the suspect.
Yeah but comparing a fingerprint to a finger is a simpler test than comparing a fingerprint to another fingerprint and checking if they may be two fingers from the same person.
