Target has started closing their San Francisco stores at 6pm as a response to the increase in theft. Do you really think that this wasn't a data-driven decision, and that Target as a whole just got swept up in some kind of racist moral panic?
This is the "broken windows" theory- if you let minor crimes like shoplifting go unpunished in a city, more people will do it.
... But the hours restriction is interesting. I've noticed weird hours at the Taco Bell near my place, and this is probably purely anecdotal, but it does make me sort of wonder if there's something unique to Taco Bell making it hard for them to flesh out their hours.
