This review focuses on terrorism and extremist crimes, including ideologically motivated hate crimes. Research on these topics has become more rigorous in recent decades, and more scholars have engaged in original data collection. Our assessment found a burgeoning literature that increasingly includes the application of integrated theories, but gaps remain as few studies examine life-course and critical approaches. Our review of the policing of terrorism found a limited evidence base for counterterrorism initiatives. We also found that court/sentencing issues are understudied. We suggest improving data quality in these areas by creating a national data collection protocol on these crimes, enhancing the rigor of offender and victim self-report studies, and requiring more transparency from open-source research efforts. We propose that government agencies fund rigorous evaluations of policing strategies in the terrorism context. Finally, it is hoped that increased access to federal court documents will lead to more scholarly attention on sentencing issues.

Over a one year period from April 2021 - March 2022, Moonshot partnered with three violence prevention organizations to deliver an online interventions pilot in two Canadian provinces. The pilot advertised psychosocial support services to individuals engaging with extremist content online. Access to these services was voluntary, confidential, and anonymous by design. Our goal was to offer a secure pathway for at-risk individuals to contact a trained therapist or social worker. We built this approach around offering integrated care. Together with our intervention partners, we crafted our advertising messages and service websites to emphasize the confidential, non-judgemental support that callers would receive. Individuals who reached out were connected to an interdisciplinary team, which included a therapist, youth engagement workers, a psychiatrist, and other intervention staff who could offer services like counseling, employment support, addiction support, or simply a space to talk. Our partners were the Estimated Time of Arrival (ETA) team in Ontario, and Recherche et Action sur les Polarisations Sociales (RAPS) in Quebec. The Canadian Practitioners Network for the Prevention of Radicalization and Extremist Violence (CPNPREV) acted as a convening and best practice provider, and supported our pilot evaluation. A description of each organization is at the end of this report. Moonshot’s intervention campaigns ran for a total of six months, and reached individuals consuming incel and violent far-right extremist content on Google Search and YouTube. Our online interventions focused on meeting individuals’ psychosocial needs, and appealed to vulnerabilities and grievances, such as anger, frustration, exhaustion, and isolation. Executive summary Key outcomes Moonshot redirected 786 at-risk individuals to our intervention partners’ websites. 22 initiated a conversation with a counselor. Four individuals formally registered and engaged with a service provider for several months, in addition to those who accessed virtual counselling without going through the registration process. At least one person who initially shared violent impulses has been able to find positive, hopeful alternatives for the future. Moonshot’s ads reached users engaging with harmful content on Google and YouTube 44,508 times. Among the hundreds of users redirected to ETA and RAPS’ websites, 26 were watching influential incel YouTube channels and 39 had searched Google for high-risk keywords related to incel and violent far-right ideology (“looksmax org”; “1488 tattoos”). Moonshot, ETA, RAPS, and CPN-PREV established an effective multi-sectoral partnership. During our pilot program, we co-designed support pathways and risk escalation procedures for each service area, built teams’ capacity to deliver online interventions safely and effectively, and engaged at-risk audiences online. This pilot provides a blueprint for future interventions to reach and engage at-risk internet users. New iterations of this work can reach larger audiences by expanding advertising beyond the pilot platforms, strengthening and expanding cross-sectoral partnerships, and testing new ways to reach often-isolated internet users.

The Prevent counter-terrorism strategy is perhaps the most controversial government policy most people have never heard of. Public recognition of it is generally low, but opposition from Britain’s raucous Islamist scene, near total. From there, opposition has spread to sections of the far-left, and those parts of academia where Islamism and the revolutionary left intersect. This report, written by three experts on Islamism, outlines the campaign against Prevent, and argues that this is not an exceptional campaign against a uniquely flawed policy – the groups opposing Prevent have tended to criticise pretty much any counter-terrorism policy, in sine cases for a generation. The same names and campaign groups appear time after time regardless of the colour of the government of the day.

Disappointingly, ministers and officials have tended to shy away from some of these debates, allowing misinformation, and even conspiracy theory, to flourish. The forthcoming Prevent review by William Shawcross risks being dead on arrival if this continues. The authors call for a Centre for the Study of Extremism to give Ministers the tools to properly push back against campaigners, with a separate communications unit to disseminate rebuttal, and a due diligence unit. The latter is needed to ensure that government departments and the public sector are choosing their friends wisely. Too often anti-Prevent campaigners are able to grandstand against government counter-terrorism policies, whilst at the same time receiving government patronage and engagement. It should no longer be possible to run with the fox, and hunt with the hounds.

his open access book brings together a range of contributions that seek to explore the ethical issues arising from the overlap between counter-terrorism, ethics, and technologies. Terrorism and our responses pose some of the most significant ethical challenges to states and people. At the same time, we are becoming increasingly aware of the ethical implications of new and emerging technologies. Whether it is the use of remote weapons like drones as part of counter-terrorism strategies, the application of surveillance technologies to monitor and respond to terrorist activities, or counterintelligence agencies use of machine learning to detect suspicious behavior and hacking computers to gain access to encrypted data, technologies play a significant role in modern counter-terrorism. However, each of these technologies carries with them a range of ethical issues and challenges. How we use these technologies and the policies that govern them have broader impact beyond just the identification and response to terrorist activities. As we are seeing with China, the need to respond to domestic terrorism is one of the justifications for their rollout of the “social credit system.” Counter-terrorism technologies can easily succumb to mission creep, where a technology’s exceptional application becomes normalized and rolled out to society more generally. This collection is not just timely but an important contribution to understand the ethics of counter-terrorism and technology and has far wider implications for societies and nations around the world.

Protracted insurgencies and the growing threat by local affiliates of the global terrorism networks of al-Qaeda and the Islamic State (ISIS) throughout Nigeria, Somalia, and Burkina Faso have transformed on-the-ground responses to violent extremism throughout Sub-Saharan Africa. Somalia continues to grapple with the unrelenting force of the al-Qaeda affiliated al-Shabaab; Burkina Faso contends with al-Qaeda in the Islamic Maghreb (AQIM), Jama’at Nusrat al-Islam wal Muslimeen (JNIM), ISIS in the Greater Sahara (ISGS), and Ansarul Islam; and Nigeria remains encumbered by Boko Haram’s 14-year insurgency and the increasingly violent Islamic State West Africa Province (ISWAP). As serious and sustained militant and terrorist movements continue to kill thousands and displace millions, the three respective governments have altered their responses to violent extremists and terrorism, integrating civilian-led, community-based security strategies into their national counterterrorism programs. National armies and their international partners have offered some reprieve from enduring violent conflicts, but in many cases have failed to offer comprehensive protections to all civilians. Civilian counterterrorism militias emerged to provide security to vulnerable communities and were quickly recognized as an alternative to state-sponsored counterinsurgency campaigns. However, once these counterterrorism militias were enlisted and absorbed into the national security apparatus, new—albeit long-established—challenges quickly emerged. Localized counterterrorism campaigns have at times devolved into vengeful operations against ethnic rivals as well as opportunities to carry out illicit activities such as extortion, drug trafficking, and looting. The benefits and drawbacks of civilian counterterrorism militias remain consistent across different regions. The strategy is cost-effective and practical as civilian defense forces are often cheaper than formal security units, such as the national army and the police. There is a ready pool of potential local recruits to safeguard vulnerable communities, and they are knowledgeable about the communities they protect. Most importantly, civilian troops establish a level of community loyalty that can be difficult to achieve with national armies. Significant drawbacks of civilian forces are that troops can become unreliable and difficult to control if not properly managed. Furthermore, without strong and effective oversight mechanisms, civilian troops are capable of undermining government authority, rule of law, and governance. Unfortunately, if not carefully executed, civilian forces could deteriorate into armed criminal networks,1 transforming from vanguards of safety into long-term sources of instability and insecurity.

Abstract: This Element explores the topics of terrorism, counterterrorism, and the US government’s war on terror following the September 11, 2001 terror attacks. It draws on insights from Austrian and public choice economics. First, it discusses the foundations of the economics of terrorism, emphasizing that the behaviors of terrorists and counterterrorists are purposeful and goal-oriented. It then considers the economics of counterterrorism policies and the importance of institutional change for reducing demand for terrorism. Next, it focuses on three dilemmas facing liberal societies in relation to counterterrorism efforts. The Element then provides an assessment of the US government’s war on terror. It discusses the origins of the war, whether it can be judged a success or a failure, and some of the main effects both abroad and within the United States. The Element concludes by putting forward several areas for future research.

From the document: "Ten years ago, U.S. national security agencies grew concerned about a relatively new and powerful weapon used by terrorists: the World Wide Web. What had begun as an effort to connect end users from across the world to share information and to serve as a force of human liberation, instead began to be used as a tool for destruction of life. Terrorists were exploiting technology companies' lax content moderation policies to recruit new members, spread violent extremist ideology, and plan terrorist attacks. [...] Technology companies and governments have spent the past decade trying to better address the evolving threat of terrorist and violent extremist content online (TVEC). However, there are few studies examining just how effective these efforts have been, where we are today in managing the problem, and wherein lie gaps for improvement. This paper argues that companies' efforts to deal with TVEC have been hampered at the outset by a tendency to define TVEC extremely narrowly. [...] This paper also explores the idea of ethical obligations and norms as an alternative to a legally required definition. On the technical side, this paper finds that even if there was consensus on the legal and ethical questions surrounding TVEC, the technical tools currently available are no panacea. Trade-offs across efficiency, scalability, accuracy, and resilience are persistent. Current technical tools tend to disadvantage minority groups and non-English languages. They are also less robustly implemented across small and non-U.S./European firms, generally either because they are left out of inter-firm initiatives or because they lack resources and capability. This paper does not claim to cover every issue relevant to TVEC; however, it highlights several important gaps that could be addressed by policymakers and tech companies and identifies avenues for future research."

The nexus between terrorist and transnational organized crime (TOC) networks in West Africa presents one of the most significant security challenges. Both networks undermine governance and the rule of law and cooperate on a multitude of levels in a complex web of mutual beneficial arrangements. Therefore, this nexus presents a mutually enforcing mechanism that supports and accelerates regional destabilization. This paper argues that the risks emanating from this cooperation are not limited to terrorism financing alone as terrorist groups also use their cooperation with TOC networks to gain access to resources needed for their activities, such as arms and ammunition. Finally, such cooperation also allows terrorist groups to carve out spaces that allow them to control the local population while at the same time provide security for local licit and illicit economic activities. Therefore, this cooperation is in some cases also a tool through which terrorist groups can gain support and acceptance among the local population. Therefore…

  , tackling this nexus must involve both the regaining of territorial control from terrorist groups by the respective governments as well as the strengthening of governance structures. Both aims should also be attempted concurrently. This paper presents a range of recommendations for German and European decision-makers that primarily aim to disrupt the entry as well as exit points of the flows of illicit goods of the region. Given the current challenges European and German projects face when cooperating with some of the governments in the region, an emphasis on increasing regional cooperation in West Africa seems advisable. In particular, the paper suggests strengthening national and regional law enforcement and border control capabilities, especially within the coastal states of the Gulf of Guinea. Increased cooperation with the Intergovernmental Action Group Against Money Laundering in West Africa (GIABA), increased support to strengthen the management and control mechanisms for national parks, and intensified exchange mechanisms, such as the West Africa Police Chief Committee (WAPCC) of Economic Community of West African States (ECOWAS), could be contemplated. In addition, German and European decision-makers could encourage and support governments in the region in their efforts to intensify the use of existing regional mechanisms such as the ECOWAS sanctions mechanism, as well as increase the participation of regional states in the United Nations Office on Drugs and Crime (UNODC)-World Customs Organization (WCO) Container Control Program and INTERPOL’s West African Police Information System (WAPIS) as possible priorities.

  Terrorism remains a significant threat to the internal security of the European Union. Terrorists operate across borders, leveraging new technologies and modi operandi to target innocent people. EU law enforcement authorities, in particular the counter-terrorism community, remain vigilant and united in countering the threat. The EU Terrorism Situation and Trend Report (TE-SAT) 2023 contributes to this effort, by presenting prevalent terrorism trends in the EU. Terrorism constitutes an attack on our society intending to create fear and chaos among EU citizens. In 2022, 16 terrorist attacks took place in the EU and an additional 12 attacks failed or were foiled. While the attacks directly affected seven Member States, more Member States arrested suspects in terrorism-related cases. Tragically, four people were killed in terrorist attacks in the EU, two resulting from jihadist attacks and two from a right-wing terrorist attack. We honour the memory of all those lost to terrorism in 2022 and in previous years.

  Member States continue to view jihadist terrorism as the most prominent terrorist threat to the EU despite the fact that the number of jihadist attacks has decreased compared to 2021 and 2020. The threat from right-wing terrorist lone actors, radicalised online, remains significant. Left-wing and anarchist terrorists and violent extremists continue to pose a threat to public safety and security in the EU. Additionally, the spread of propaganda online and its potential for radicalisation remains a key concern. Social isolation and the lack of a solid support system remain key vulnerabilities which terrorists take advantage of in order to propagate their messages and to recruit new followers. This is particularly worrying with the increasing number of young people, including minors, exposed to online terrorist propaganda. Furthermore, the terrorist and violent extremist environment is becoming more decentralised and volatile. Diffuse actors connect and inspire one another, uniting behind grievances beyond ideology or group affiliation. This context is ripe for self-radicalisation and for lone actors to begin engaging in attack planning, and poses significant challenges for preventing and combating terrorism and violent extremism in the EU.

The beginning of the millennium saw an increased political focus on the threat from international terrorism, heightened by the attack on the Twin Towers on 11 September 2001. Only one year before 9/11, new counter-terrorism legislation had been passed in the UK. Designed to reform and extend state powers found in previous counter-terrorism legislation, the Terrorism Act 2000 gave increased powers to the Home Secretary and the police. It moved the focus of counter-terrorism to all forms of domestic and international terrorism, rather than just Northern Ireland-related terrorism. In 2003, the Government introduced its counter-terrorism strategy, CONTEST. Now in its fourth iteration, CONTEST aims to reduce the risk to the UK from terrorism with four objectives:

• Pursue: to stop terrorist attacks

• Prevent: to stop people becoming terrorists or supporting terrorism

• Protect: to strengthen protection against a terrorist attack

• Prepare: to mitigate the impact of a terrorist attack

Although statistics relating to terrorism and the use of counter-terrorism legislation have been collected by the Home Office since the 1970s, the publication (and consistent collection) of data was halted in 2001. This briefing examines the available statistics on terrorism in Great Britain including:

• Deaths due to terrorism

• The use of stop and search legislation

• Terrorism arrests

• Pre-charge detention periods

• Prosecutions and convictions for terrorism

• Terrorist prisoners

• The use of TPIMS

• The number of foreign fighters fighting in Syria

To several governments, modern international terrorism cannot be handled adequately within the ordinary criminal justice system. To fight terrorism (including the criminalization of certain “abstract danger”, preparatory activities such as terrorist training, membership in a terrorist organization) more effectively, criminal law had to be adapted.

In the field of terrorism research, the violent radicalisation of individuals towards perpetrating acts of terror has been the subject of academic enquiry for some time. One core focus by social scientists has been the role of narratives in this process. Narratives have the ability to present a socially constructed version of reality which serves the interest of the narrator(s). In the context of terrorism, by depicting violence as a viable antidote to individual vulnerabilities, the narratives purported for propagandistic purposes have the potential to thwart perceptions of instrumentality (a key characteristic of violent radicalisation). In order to prevent this from happening, researchers and counter-terrorism practitioners have increasingly sought to explore the potential for counter-narratives; targeted interventions that challenge the rationalisation(s) of violence purported in dominant narratives which, in turn, reconstructs the story. However, there is overwhelming consensus in both government and academic spheres that the concept of the counter-narrative is underdeveloped and, to date, there has been no synthesis of its effectiveness at targeting violent radicalisation-related outcomes.

The objective of this review was to provide a synthesis of the effectiveness of counter-narratives in reducing the risk of violent radicalisation.

The introductory chapter of this book presents the concepts of the benefits inherent in the study of comparative approach for an effective counterterrorism response on the local law enforcement level and overviews the inception of the project. Throughout the twentieth century and into the twenty-first century, especially after the events of September 11, 2001, the legitimacy of law enforcement practices has been cited as a major concern for international criminal justice. As policing practitioners and scholars throughout the world shifted focus from a traditional reactive, crime control stance to the need for accountability mechanisms to ensure the s- port of citizenry in combating crime and terrorism, the democratization of policing was seen as the best mechanism for achieving long-term gains in public order at the same time as protecting human rights. While the need to maintain human rights remains an important issue, balancing these concerns with the important public safety interests of societies is paramount.

Will Terrorism End? examines this question by tracing the history of terrorism and terrorist groups. Over time, terrorist groups have risen and fallen, sprouting offshoots, disbanding, or being destroyed by governments. This book argues that terrorism is cyclical, and therefore will neither entirely disappear nor become fully dominant. Because terrorism is a relatively easy tactic for individuals and groups to adopt, it may never go away, but we have developed countermeasures to minimize its effects and continue to innovate ways to reduce its presence in our world.

Roger Douglas compares responses to terrorism by five liberal democracies—the United States, the United Kingdom, Canada, Australia, and New Zealand—over the past 15 years. He examines each nation's development and implementation of counterterrorism law, specifically in the areas of information-gathering, the definition of terrorist offenses, due process for the accused, detention, and torture and other forms of coercive questioning.

Douglas finds that terrorist attacks elicit pressures for quick responses, often allowing national governments to accrue additional powers. But emergencies are neither a necessary nor a sufficient condition for such laws, which may persist even after fears have eased. He argues that responses are influenced by both institutional interests and prior beliefs, and complicated when the exigencies of office and beliefs point in different directions. He also argues that citizens are wary of government's impingement on civil liberties and that courts exercise their capacity to restrain the legislative and executive branches. Douglas concludes that the worst antiterror excesses have taken place outside of the law rather than within, and that the legacy of 9/11 includes both laws that expand government powers and judicial decisions that limit those very powers.
