So in other words, if you show it 100 random people and ask who did it, it will tell you to arrest 15 people, with a 15% chance not a single one of them is guilty?

(assuming it will operate independently for every individual you show it)

That's great.

Of course, putting such a system on public cameras, scanning large amounts of people, is about as stupid as some of the biggest disasters in medicine (using a 98% effective drug on random people, regardless of whether it would help them or not. You REALLY want to check what happens if you're wrong before applying it to a large number of people)
