If a widespread facial recognition system were deployed, the false positive rate would probably be a lot greater than would be acceptable. For what it's worth, this paper I found claims that humans are 97.53% accurate, whereas one particular deep learning algorithm was 99.80% accurate [0]. If you ask me, 99.8% accuracy means large cities will pretty regularly experience situations where there will be serious negative consequences from misidentification.
