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).

No, I'm not. He specifically mentioned broken window theory elsewhere.

There are multiple interpretations of the data, and the Wikipedia page I cited goes through the many possibilities.
