But then it can't possibly be the "people just believe computers" effect, because the article explicitly states the police realized the computer was wrong.

Then in this case it's the same as phishing emails. People know it's wrong, and yet still follow along anyways.

This is not necessarily a forgone conclusion, but occurs to often to dismiss.

Nothing indicates that it is specific to algorithmic facial recognition. Actual humans make mistakes identifying suspects all the time. At the very least, the article should address that and compare the reactions, to prove people are more likely to act despite knowing better when the id was made by a computer.

A reasonable point.
