Can happen without technology too, of course. I was nearly thrown out of a pub before I opened my mouth and the staff realised I wasn't the person who caused trouble there the week before.

I work in a factory that makes electronic circuit assemblies. Green fiberglass rectangles with electronic parts soldered to them.

We have automated camera systems that look at each assembly, and identifies whether or not everything is perfect, or if there is a potential issue that a human has to look at.

Despite being nearly 2D, and despite everything being the same distance from the camera, moving at a known speed, with well-controlled lighting, our false call rate is about 10,000 PPM. That's 1%. And our electronic circuit assemblies don't wear glasses or hats, or makeup.

The police claiming that they have a false call rate of 1 in 33,000 (30 PPM) doesn't make sense to me.

Is your false call rate 1 false positive per 100 parts or 1 false positive per 100 positive claims ?

If you have 1 false positive per 100 positive claims and the police have 1 false positive per 33000 IDs the numbers would not be incompatible.

1 false positive per 100 parts.

[bens_dad]

How many true positives ?

I guess if the police system doesn't claim many hits, it cannot generate many false positives.

[armiphlage]

About 100 PPM true positives, or 0.01%.
