Wow, that's very cool. :eusa_clap

A device long used by hat stores, to measure the size and shape of a customer’s head, now helps police of Norwalk, Conn., to identify criminals. According to sponsors of the new method,who use it in conjunction with fingerprinting, no two men have heads of exactly the same shape. Therefore, the perforated contour patterns produced by the device will afford a check on a suspect’s identity, and may prove particularly valuable if he has attempted to alter his fingerprints by chemical or surgical means. Since he cannot change the contour of his skull, this would remain as a telltale clew to his identity.

Harpo invented this much earlier. lol
