I remember going out to the Safeway near Castro sometime late at night, and while minding my own business I see two guards doing an NFL chase and tackle on a shoplifter which attempted to run out. That was a while ago, 2015 or so. I understood it's a very routine thing, happened every night sometimes multiple times.
SF to me feels like a cautionary tale of a city that had everything going for it but mismanages its fortunes all the way to the ground, very much like a national Resource Curse.
