A report from Obvious Land has revealed that San Francisco's public transportation system, which has raised revenue, improved customer safety, and is cleaner and more orderly than ever, has been successful in reducing crime. The report suggests that when installing new gates that make it impossible for fare-evaders to evade, they significantly improve the subway system. This change was opposed by criminal justice reformers, who argued that cracking down on crime wouldn't make the subway safer. However, the report concludes that with just a little effort, enforcement can make a significant difference.
