Social media provide novel opportunities for street gangs to operate beyond their traditional borders to sell drugs, recruit members and control their territory, virtually and physically. Although social media have contributed to the means available to street gangs today, it does not mean that every gang agrees on their use. Drawing on different perspectives (ex-gang members, law enforcement) on gangs using a multi-method design in a London borough, the current study shows that social media have polarized gangs, resulting in two distinct types of digital adaptation. The proposed division of ‘digitalist’ and ‘traditionalist’ gangs is rooted in Thrasher’s (1927) dictum that no two gangs are alike and explains how some gangs prefer to keep a low profile, thus, avoiding social media use. ‘Digitalists’, by contrast, prefer to use social media as a way to gain reputation and territorial expansion. They use it to brand themselves and to appear attractive for recruits and customers alike. These differences can be theoretically explained firstly as a generational gap, meaning that younger gang members prefer the use of social media; and secondly, by how well established a gang already is, as newer gangs need more attention to establish themselves.

  Social media use by youth is nearly universal. Up to 95% of youth ages 13–17 report using a social media platform, with more than a third saying they use social media “almost constantly.”  Although age 13 is commonly the required minimum age used by social media platforms in the U.S., nearly 40% of children ages 8–12 use social media. Despite this widespread use among children and adolescents, robust independent safety analyses on the impact of social media on youth have not yet been conducted. There are increasing concerns among researchers, parents and caregivers, young people, healthcare experts, and others about the impact of social media on youth mental health.5, 6 More research is needed to fully understand the impact of social media; however, the current body of evidence indicates that while social media may have benefits for some children and adolescents, there are ample indicators that social media can also have a profound risk of harm to the mental health and well-being of children and adolescents. At this time, we do not yet have enough evidence to determine if social media is sufficiently safe for children and adolescents. We must acknowledge the growing body of research about potential harms, increase our collective understanding of the risks associated with social media use, and urgently take action to create safe and healthy digital environments that minimize harm and safeguard children’s and adolescents’ mental health and well-being during critical stages of development.

From the document: "This Advisory calls attention to the growing concerns about the effects of social media on youth mental health. It explores and describes the current evidence on the positive and negative impacts of social media on children and adolescents, some of the primary areas for mental health and well-being concerns, and opportunities for additional research to help understand the full scope and scale of social media's impact. This document is not an exhaustive review of the literature. Rather, it was developed through a substantial review of the available evidence, primarily found via electronic searches of research articles published in English and resources suggested by a wide range of subject matter experts, with priority given to, but not limited to, meta-analyses and systematic literature reviews. It also offers actionable recommendations for the institutions that can shape online environments--policymakers and technology companies--as well as for what parents and caregivers, young people, and researchers can do."

Whereas outlaw motorcycle gangs (OMCGs) were originally perceived as uncivilized white men grouped around a passion for motorcycles and riding, they have now become increasingly associated with organized crime. Governments have defined them as a crime policy priority, resulting in a broad-scale law enforcement offensive aimed at reducing OMCG-related crime, reducing the number of clubs and chapters, and reducing interclub tension. The way in which the general public perceives OMCGs and the attitude toward OMCGs is largely influenced by media coverage on the subject, and in recent years OMCGs have become a popular topic. As public perceptions, policymaking, and media coverage influence each other, this paper seeks to explore the contemporary representation of OMCGs and law enforcement in the Meuse Rhine Euregion by means of analyzing regional newspaper articles from 2010 up to and including 2016. The theories used for this analysis are Quinn and Koch’s criminality typology and the situational crime prevention framework. Results demonstrate that the public image of OMCGs indeed centers around (organized) crime, and that even when events not involving crime are covered, the newspaper article focuses on law enforcement working toward containing the risks of OMCG-related crime and monitoring motorcycle clubs. The public image of law enforcement measures against OMCGs therefore relies heavily on police actions and, to a lesser extent, on administrative authority reducing not only crime opportunities, but also making OMCG life in general less attractive.

Does social media lead vulnerable individuals to resort to violence? Many people believe it does. And they respond with online censorship, surveillance and counter-speech. But what do we really know about the Internet as a cause, and what do we know about the impact of these reactions? All over the world, governments and Internet companies are making decisions on the basis of assumptions about the causes and remedies to violent attacks. The challenge is to have analysis and responses firmly grounded. The need is for a policy that is constructed on the basis of facts and evidence, and not founded on hunches – or driven by panic and fear mongering. It is in this context that UNESCO has commissioned the study titled Youth and Violent Extremism on Social Media – Mapping the Research. This work provides a global mapping of research (mainly during 2012-16) about the assumed roles played by social media in violent radicalization processes, especially when they affect youth and women. The research responds to the belief that the Internet at large is an active vector for violent radicalization that facilitates the proliferation of violent extremist ideologies. Indeed, much research shows that protagonists are indeed heavily spread throughout the Internet. There is a growing body of knowledge about how terrorists use cyberspace. Less clear, however, is the impact of this use, and even more opaque is the extent to which counter measures are helping to promote peaceful alternatives. While the Internet may play a facilitating role, it is not established that there is a causative link between it and radicalization towards extremism, violent radicalization, or the commission of actual acts of extremist violence.
