NPR Planet Money: San Francisco car crime has plunged; how much credit does Flock deserve?

NPR's Planet Money examines San Francisco's steep drop in car theft and break-ins. City leaders credit Flock plate readers, but the author notes the best available study is not peer reviewed, that cameras mostly sit at intersections rather than in residential areas, and that several other factors changed at the same time. Misuse audits and a pending state-penalty push are part of the picture.
