The theoretical use case is that somehow it helps tracks suspects. Obviously that's only reality in a case where you either have broad facial recognition profiles across the population, or you have additional facial recognition cameras in an area of interest, both of which raise additional concerns. In reality I suspect this is a solution in search of a problem. I was witness to a serious hit and run, caught video of the person who fled - clear pictures of the person, car, license plate. Should have been the easiest case in the world to handle but leos didn't even ask for the footage. Only group that has ever accepted dashcam footage from me is insurance. Most law enforcement agencies have a lot more data than they can reasonably handle, but it's easier to complain about a lack of data than explain you can't actually analyze it.
