jfruh writes "Cynthia Navarro starts her sessions training police to mine social media in dramatic fashion: by quickly finding data about the officers themselves. She also provides information about who's where online — for instance, younger suspects will probably be focused on Twitter, while older folks are on Facebook or even MySpace. 'How much information can be gathered? Look no further than the 2011 Stanley Cup Riots in Vancouver, BC. By examining hours of video and social media posts made during the event, a taskforce was able to post pictures of over 100 suspected rioters online — over 30 of which were identified by police.' It's all part of a drive to teach even nontechnical police officers at small and midsized departments how to use social media to track suspects."
