A defining characteristic of the 21 st century has been the rapid growth of social media. The
current study looks at law enforcement efforts in social media to inform the public, shame
criminals and criminal activity, and to seek aid from the community in investigations. This study
fills a void in current research by empirically evaluating police-posted videos and the rate that
these videos lead to both tips and arrests. Implications for how these videos can effectively
assist in criminal investigations are discussed.
