It also stops when there is nothing left to loot. Here in NJ there aren’t many businesses that can be reached by a critical mass of gibsmedats; the cities died and people shopped in suburbs instead. My town (between Newark and Jersey City) has a Walmart; it is easy to restrict access from those two dumps to it. Rivers help, as do cops who do the jobs they are paid for. Also, any post-1960s construction probably factors in these things (when designing vehicle access and such; they can’t walk back with their stolen sh!t.).
When those stores close permanently there will be caterwauling about corporate systemic racism causing food and shopping deserts.
I grew up in Jersey City and Union City. When I got my first car (a crappy Chevy Monza), I drove between Newark and Jersey City multiple times. I don't remember a town between the two, but I moved to Los Angeles in 1976 and never went back, so things probably changed a lot in the ensuing 44 years. Maybe a town grew up between JC and Newark?

In Chicago, this school of architecture was called “riot rennisance”. Very small high windows are another feature. Look at Walgreens’ “standard building”.
