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.

While countries differ significantly in how they handle terrorism, in the west, criminal justice systems tend to treat terrorism similar to other crime, with police, prosecutors, judges and courts, and penal systems carrying out similar functions of investigations, apprehension, charging, convicting, and overseeing punishments respectively. While there is a robust literature on deterrent effects for crime, there is a dearth of research when it comes to terrorism. This despite evidence of significant overlaps between crime and terrorism. We address this gap in the literature with a unique dataset covering terrorism offending, arrests, charges, convictions, and sentencing over 16 years in 28 EU-member states. Applying a dynamic panel data model, we find that the probability of apprehension and punishment has an inverse relationship with terrorism offending. Conversely, the rate of charged individuals is associated with a small increase in the terrorism offending rate. The results for sentence length are less clear, with either negligible, or small iatrogenic effects. The results demonstrate that the overlap between crime and terrorism may extend to general deterrence. These findings should be informative for both the research agenda and policy discussion.

What’s new? Nigeria has seen a proliferation of vigilante organisations to fight crime and protect the public. These range from small bands of volunteers in villages and city neighbourhoods to large structures established by state governments. Some have mandates to safeguard particular regions or ethno-religious groups. Why did it happen? New organisations are emerging largely because the federal government and police force are increasingly unable to curb insecurity across the country. Many ethnic groups and communities feel a sense of siege, prompting them to resort to self-defence. Why does it matter? In many parts of the country, vigilante groups are filling security gaps. With poor training and supervision, however, their members are prone to human rights abuses and vulnerable to capture by politicians and other elites. In some cases, their activities could aggravate intercommunal tensions, heightening risks of conflict. What should be done? To provide better security and counter impunity, the federal government should pursue police reform and bolster judicial capacity. Some devolution of policing powers to state and local levels is needed. Federal and state authorities should develop regulations to better manage vigilante groups and risks associated with their operations.

Since 2001, violent sub-national groups with disparate ideologies and motivations have been working together to further their objectives. They are collaborating, sharing each other’s tactics, and learning from one another’s successes and failures. What is the background or historical context of the crime-terror nexus, and what challenges does it present to U.S. homeland security practitioners? This thesis uses a case study approach to examine the history of the nexus between transnational criminal organizations and foreign terrorist organizations. The three case studies are then used as the data for the analysis chapter, which shows the historical and emerging relationships between states and the three violent sub-national groups. The three case studies suggest the activities of these violent sub-national groups are protean in nature; they are best described by analysts as falling into the “gray area phenomenon.” The three case studies, the analysis, and conclusion of this thesis support the recommendation that more effort needs to be placed on intelligence collection, especially at the domestic and local levels.

Guatemala is currently experiencing a full-blown crisis of the democratic state. An unholy trinity of criminal elements—international drug traffickers, domestically based organized crime syndicates, and youth gangs—is effectively waging a form of irregular warfare against government institutions, with devastating consequences. The police, the judiciary, and entire local and departmental governments are rife with criminal infiltrators; murder statistics have surpassed civil-war levels in recent years; criminal operatives brazenly assassinate government officials and troublesome members of the political class; and broad swaths of territory are now effectively under the control of criminal groups. Guatemala’s weak institutions have been unable to contain this violence, leading to growing civic disillusion and causing a marked erosion in the authority and legitimacy of the government.

The intent of this monograph was to explore the multiple dimensions of Colombia's ongoing crisis and inform the public debate regarding the challenges faced by the statesmen, intellectuals, military strategists, and others who take on the responsibility to deal with that crisis. Hopefully, it will also generate serious reflection about the tough choices Colombian, U.S., and other global leaders face. The author points out, first, that the Colombian paramilitary self-defense forces represent some important sectors of society, and enjoy more popular support from Colombian society than the insurgents. Second, the paramilitaries have developed into a powerful irregular force that is proving itself capable of challenging Colombian guerrillas. Third, while they commit horrendous atrocities, they have been successful where the state has not. Therefore, the paramilitaries are seen by many as a viable solution to the conflict. Finally, he argues that, until the segments of the society represented by the paramilitaries are--somehow-- incorporated into the solution to the Colombian crisis, there will be no solution.
