How much should you tip?

We dig into the data around surveillance cameras, like CCTV and Flock automatic license plate readers, and talk about whether they prevent crime and make you safer.  An earlier version of this episode incorrectly stated that Flock makes license plate readers for police cars. It has been amended to state that Flock makes stationary cameras, and to more clearly explain a law that has restricted mobile plate readers in police cars.

Clare interviews Dr. Katie Sharkey, professor at the Wake Forest University School of Medicine, to find out – digging into the data on time changes, the body clock, and how proposed changes to the time system could affect our well-being.  Have a question we should answer on the show?
