Advanced Asian cities which combine rapid zero tolerance policing with the resulting social conformity don’t have these issues. There has been a rise in drug abuse but it tends to stay out of the public view, again due to policing.

I remember visiting nyc and seeing people shooting up in the street while the police were watching. Obviously the problem is lack of enforcement- and if petty crimes aren’t enforced even with just small punishments, then more serious crimes accelerate.

For readers who run across this, this is referred to as the Broken window theory:

And despite the commenter stating it as fact, both here and elsewhere, the idea is very much controversial, and far from proven.

You may be misunderstanding his point.

I think he's pointing out that people who commit serious crimes usually have a prior history of smaller, petty crimes that they were not given meaningful punishment for.

The data certainly supports this observation, and I can dig out supporting evidence if it's in doubt (at least in NYC, Dublin, and London. I'm not familiar with SF).
