It is across the country at this point. IIRC Gascón, the former DA in SF is now the DA in LA and pursuing similar policies, while there are similar policies implemented or being implemented in other cities like Chicago and New York.

People will blame the police, but I think this is a symptom of far greater issues in society, whose costs have been offloaded leaving the police to (poorly) manage it because that's probably the best they can do and everyone else is too busy avoiding culpability.
