As far as the police are concerned, I think those two examples would be the most important ones. As for “crime”, I would qualify that and say “serious crime”. I'm not sure that facial recognition should be used for common theft, for instance, given the risks of the use of facial recognition for privacy and other democratic rights, but it can certainly be acceptable for serious crimes, such as missing children, and for other compelling state purposes, such as in the border context to ensure that people of concern can be identified at the border while not impeding the flow of travellers to the country. To me, the necessity of identifying people of concern at the border in that context would be a compelling ground.
