People make a lot of noise about SF being a place where innovation happens, but criminals aren’t doing any of that.
What you’re likely getting in SF is there being no meaningful gap between the rich areas of SF and the poor. In larger cities you aren’t going to get hyperventilating about “person driving through [high crime neighborhood] was car jacked” but you would if it was [rich low crime neighbourhood] - but the general case means that the majority of such crimes don’t get TV coverage.
What is happening in SF is you have a large swathe of rich and upper middle class folk actually living in and around lower income neighbourhoods they’ve been able to avoid when they live in other cities. They rightly go “this crime is bad”, but their reason for it being bad is that for the first time they’re directly exposed to it.
These are the people who say “we should ban homeless people”, but don’t give a shit what actually happens to them: they can remain homeless, what matters is that the homeless people don’t impact their lives.
