An emerging methodology with technological roots – flash mobs – enables individuals using social networking sites (e.g., Facebook.com, Twitter.com, or Meetup.com), instant messaging and email to gather at a particular location, date and time and carry out legal or criminal activities (e.g., sabotage, robberies, and beatings). While the majority of flash mobs have somewhat humorous characteristics, increasingly, flash mobs have been an instrumentality of crime. Criminal flash mobs are another example of the conjoining of illicit activities with technologies, such as cyber-based identity theft, online fraud and Internet-induced extortion, to name a few.
