A strong conclusion from a weak study. I do think the way the police intervened probably wasn’t effective- a one shot intense enforcement effort. A counter example is my kids school. Their was a real problem with people speeding through the school zone. School district police started showing up at least one a week for about 6 months and occasionally after that. I don’t have quantitative results, but qualitatively speeds have remained down for years afterwards, especially because they still park a police car there every month or two. I’m not saying speed enforcement is the right solution generally, but done correctly in the right circumstances it does seem like it can lead to persistent change.
