SF still has a lot of work to do but Chessa Boudin is no longer running the SF DA's office.
The folks running in shoplifting and robbery gangs are not stealing a loaf of bread to feed their starving children, criminality is their profession.
Yes, poverty and crime do correlate strongly. Although be careful about conflating violent crime and property crime with each other.
That said, correlation is not causation. There is likely /some/ causative element between poverty and crime, but it is not absolute, rather poverty is also strongly correlated with other non-criminal behaviors that both lead to poverty and lead to crime. There is definitely a cultural element in wealthy countries to generational poverty, just as there is a cultural element to criminality.
If we can break that cycle for people, it benefits society as a whole, and I think it's worth investing what we can as a society into doing so, however current research certainly doesn't support deferment of responsibility for criminality because of poverty.
Except that's just not true. The US has thousands of mostly independent police departments. Some use civil asset forfeiture (fewer, now that the supreme court has stepped in). Many don't.
What a small town in Alabama does has no connection with what the SFPD does.
You don't have to catch and convict them every time to be effective. If you caught and convicted even 2% of the crimes, crime would be massively lower within 6 months, because it's the same people doing it over and over.
