I guess we need a comparative term to appreciate the sentence: >The police said that since 2017, 58 people had been arrested after being identified by the technology. I mean, 58 people in 2 years is like 2-3 per month, if the scanned faces were (say) 1,000 per month is one thing, if they were (still say) 1,000,000 per month it would be another. And it all depends on how the 998 or 999,998 not-identified people data (if any) is used (or stored). The analogy of: >a police officer standing on the corner looking out for individuals and if he recognizes somebody, saying, ‘I want to talk to you.’” is fine and dandy exactly because those that were not recognized are not "talked to" nor any note about them is taken by the officer.
