All kinds of problems with this take, but the biggest one is that San Francisco has never been "under progressive rule." Seriously, Willie Brown, Gavin Newsom, Ed Lee, London Breed? One machine politician after another.
In San Francisco, it's far too obvious that crime has worsened under progressive rule.
In the '90s, convenience stores didn't lock shelves, and chains didn't flee.
So did crime actually go down? Did people stop reporting it? Or is the government cooking the data?
