Social media has become a part of everyday life. All types of real-world behavior are now showcased online -- including criminal behavior, bullying, threats and the glorification of violence. Increasingly, youth associated with antisocial peer groups -- such as neighborhood-based "crews" engaging in violent rivalries -- use social media as a tool to create criminal opportunities and amplify conflicts. Unfortunately, in many cases, this type of social media usage can lead to real-life violence or other serious ramifications, such as arrest. Volume 1 of the Crime Commission's series, "Social Media & Real-World Consequences," provides an overview of the ways youth are communicating on social media and the associated risks of these communications turning into real-world violence.
