> Transit, especially if it’s made free or if fare-jumping is easy, allows both criminals and drugged-up disorderly types to reach otherwise peaceful neighborhoods. And since apartment complexes A) are cheaper to live in than single-family houses, and B) usually come with inclusionary zoning requirements that require any new complex to include some poor tenants, they also mean more poor people in the neighborhood. The author identified the symptoms, but fell short of finding the cause. Drug dealers typically live in well-connected areas as they have people come to them, not the other way around. And they can afford to, since it's a risky, but lucrative profession. All those "disorderly types" are not drugged up (at least not enough) - they're on their way to get their fix. If they had enough they would be at home, being all drugged up without a care in the world. It's a difficult problem because those who survived long enough in this line of work learned how to not draw attention to themselves from both the law and their competitors.
