Update from WWJ News Radio today:

  1. A supervisor must review all the evidence before an arrest can be made.
  2. Facial recognition results cannot be used in photo line ups.

Considering that software is going to return a best match even if there is no exact match, and that the greater the pool of photos considered, the closer that best match will appear to be to an exact match, this makes sense.

Facial recognition can't detect its own false positives and even a human can't differentiate between identical twins so photos alone are insufficient. Facial recognition can narrow the pool of suspects but additional evidence beyond photos is necessary to avoid false positives.


"That is, literally, perhaps one of the most counterintuitive things you could do. Because it's going to already produce look-a-likes," [DPD Chief] White said. "In other words, you're not going to put a suspect's twin in a line up."
It should be noted that when innocents are convicted, true criminals escape justice. For that reason, true law and order advocates are very much against convicting innocents.
