OK, sounds like the biggest issue is not the recognition algorithm itself (can be replicated or bought quickly) but the acquisition of databases of people’s identities (takes time and maybe consent earlier on). They can definitely come together, but otherwise, consider the possibilities (a) a city only uses face recognition for narrow cases like comparing video footage to a known suspect while not being able to do face-rec for the general population, and (b) a city has profiles and the ability to identify all its citizens for some other purpose but just doesn’t have the recognition algorithms (yet).
