Imaging explaining to a jury:
A statistical model says that there is a 99% chance these two finger prints belong to the same person. We don't know how this model works and it was not programmed by a human. We will be taking no further questions.
The jury: sounds like magic to me! Sounds good!
If we rig the jury to all be Silicon Valley investors and CEOs, you just have to say "AI" and you'll win the case.
Imagine finding a suspect with this method, and not taking their actual finger prints to check if the match is correct.
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.
You could hypothetically show the jury literally ALL of the math!
