Social media, and Twitter in particular, have become important sources for journalists in times of crises. User-generated content (UGC) can provide journalists with on-site information and material they otherwise would not have access to. But how they source and verify UGC has not yet been systematically analyzed. This study analyzes sourcing and verification practices on Twitter during the Brussels attacks in March 2016. Based on quantitative content analysis, we identified (1) the journalists and news organizations sourcing during the attacks, (2) classified different forms of sourcing and verification requests, and (3) analyzed the sourced UGC. Results show that sourcing on Twitter has become a global phenomenon. During the first hours of the attack, journalists rely on UGC. Their sourcing and verification practices vary widely and often lack basic verification procedures, which leads to a discussion about the ethical implications of sourcing practices.

Adam Gadahn’s Abbottabad letter offers a rare opportunity to examine how this Al Qaeda Senior Leadership (AQSL) media operative and spokesman conceptualizes and executes media warfare. In this article, I first introduce, depict, and employ the author’s Terrorist Quadrangle Analysis (TQA) as a useful heuristic for conceptualizing and representing the four interrelated components of the AQSL terrorist enterprise: political objectives, media warfare, terrorist attacks, and strategic objectives. This TQA construct is then employed to conceptualize Gadahn’s media warfare acumen. Gadahn is shown to be an adept communications warfare operative who conscientiously disaggregates and evaluates key target audiences, messengers, messaging, and media. Gadahn’s vehement critique of select ‘‘jihadi’’ groups, in particular Tehrik-i-Taliban (TTP), al-Shabaab, and the Islamic State of Iraq (ISI), is then described. Key here is how and why Gadahn denounces their indiscriminate, murderous terrorist attacks on Muslim non-combatant civilians and other protected persons as effectively subverting his intended AQSL media warfare strategy and undermining AQSL strategic and religio-political objectives. A concluding section briefly summarizes these chief findings, offers select implications for scholarship and counter-AQSL messaging strategy, and identifies study limitations.

Scholars have long seen radicalisation as a predominantly group based phenomenon, occurring largely through ‘real world,’ in person interaction. By contrast, the internet is seen as playing only a limited ‘facilitating’ role in radicalising people to violence. However, a series of attacks by far right extremists over the past decade has demonstrated that this perspective is less accurate than it once was. Almost none of these terrorists were members of extremist groups and had only engaged with other extremists on the internet. In this article, we examine the relative importance of face-to-face group interaction and physically isolated internet-based radicalization in driving individuals towards extremist violence. We do so through a detailed case study of Action Zealandia, New Zealand’s leading ideological white nationalist group. The study is based on eighteen months of infiltration of the group by one of the authors from 2019 to 2021. When interacting online, members often adopt highly extremist personas, in some cases threatening mass violence. By contrast, face to face interaction and group membership pushed the group away from extremist violence. This was due to several factors: police pressure and a lack of opportunity for the movement to grow, and the often uninspiring nature of offline interaction.
