The Pottstown Mercury, a newspaper in Pottstown, Pennsylvania, recently started posting police mugshots of wanted criminals on Pinterest. Sounds crazy, right? Well, the novel use of a social networking site known best for nail art, cupcakes, and motivational posters with bad typography has become quite a success for local law enforcement. As you can see by scrolling through the board, users are sharing comments on where police might look for each wanted man or woman.

According to an interview with police in the Pottstown Mercury, the project has resulted in a 58% increase in arrests.
