Police access to passport photos
Discussion
Seems like a good idea to me in principle, and if it helps catch more criminals then even better.
My concerns would be around how the data would be protected - the police need to be totally open about this and their systems be vetted by the same type of organisations that protect google/facebook etc from getting hacked.

Would need to have safeguards in place.
For example:
How is a match determined, and how is that presented to the investigating officer? Does a 90% match mean 90% of facial features match, or that the algorithm has determined a 90% probability that the matched identity is the suspect. What thresholds will be in place for matching... does the system show 60% matches? 75%? 85%?
What happens if it turns up multiple potential matches, and they're all properly investigated as suspects, do the innocent matches then get a record on the PNC as having been a suspect in a crime? What happens if no corroborating evidence can be found against a single matched, identity, and the case is dropped. Do they still get marked as being a suspect in a crime, simply because the computer said there was a xx% match?
What criteria should be met for these searches to be conducted. Should the police be able to upload captured images of protestors at a peaceful, lawful protest into this system to discover identies? The protests around Sarah Everards murder highlights how the police can get it very wrong.
Will this be used as evidence in court and what weight would it have; can someone be convicted where this match is the strongest evidence the prosecution has?

I would imagine that more criminals have photos on PNC than have passports.
Only those that have been arrested... So possibly not.That's why DNA and fingerprint data bases are so useful.
