People engage in terrorism and similar forms of violent extremism for a variety of reasons, political or non-political. The frequent failure to achieve what they expected or dreamed about is also usually the source of their disillusionment, and subsequently, a main reason to disengage from violent extremism. Individuals involved in terrorism often come from a diversity of social backgrounds und have undergone rather different processes of violent radicalisation. Profiles of terrorists do not work as a tool to identify actual or potential terrorists because such profiles fail to capture the diversity and how people change when they become involved in militant extremism. This study suggests a more dynamic typology of participants in militant groups, based on dimensions which represent dynamic continuums rather than static positions. During their extremist careers individuals may move from resembling one type initially into acquiring more of the characteristics of other types at later stages. When it comes to prevention and intervention measures, one size does not fit them all. The typology may be used as an aid to develop more specific and targeted strategies for preventing violent radicalisation and facilitating disengagement, taking into account the diversity and specific drivers behind different types of activists.  相似文献

Increasing anecdotal, empirical, and research evidence indicates mental disorder history is one of the several factors associated with increased risk of involvement in lone-actor terrorist activities. Currently, few studies have been conducted on the mental disorder histories of individuals assessed as at risk of involvement in terrorist activities (Meloy, J Threat Assess Manag 2019;6:93). This pilot study describes demographic, psychiatric, and criminal characteristics of a sample of Scottish individuals identified by the Prevent element of the U.K. national counterterrorism strategy, and outcome data after follow-up at 2 years. Twenty-three individuals were referred to Prevent as posing a national security risk from a county in Scotland. Their records were studied for psychiatric and criminal histories. Nine (39%) had previous psychiatric contact, all were “lone actors”, and none were embedded with organized terrorist groups. The most common diagnoses were substance use disorder, personality disorder, depression, and psychotic disorder. The sample displayed factors associated with increased risk of violence including previous offending, early behavioral difficulties, school problems, substance misuse, cluster B personality disordered traits. After 2 years, 44% of the mentally disordered group had re-offended. The offense types were generally similar to those prior to the individual being involved with the Prevent counter terrorism program. Only one of the mentally disordered group committed a further national security offense. In this sample, mental disorder history is overrepresented in individuals who come to the attention of the U.K. Prevent counter terrorism strategy. Further empirical studies with additional power are required to develop the empirical evidence base in this under-researched area.  相似文献

Background: Screens for violent convictions that are simple, accessible and parsimonious are needed, as a first stage in identifying those at high risk for further assessment. Aims: To construct and validate screening tools for minor and major violence convictions for released prisoners. Methods: Internal validation sample of 1647 serious offenders and an external validation of 46,704 general prisoners. The outcomes were binary indicators for having at least one conviction for minor and major violence. Risk factors were convictions for violence and age. Results: In the external validation sample, the instrument for risk of minor violence (PMIV) identified correctly 60.8% of male and 66.2% of female general prisoners. For risk of major violence, the instrument (PMAV) identified correctly 68.0% of male and 79.3% of female prisoners. Conclusions: The PMIV and PMAV will efficiently assist practitioners in a first stage of screening before in-depth clinical assessment of risk for future violent convictions.  相似文献

ABSTRACT

The over-representation of Indigenous offenders in Canadian prisons highlights the importance of research on the generalizability of potential static risk factors for this group. The current investigation examined whether 87 static indicators currently assessed in Canadian federal prisons were differentially present and related to outcomes (revocations, general recidivism, and violent recidivism) for Indigenous (n?=?1500) and non-Indigenous (n?=?6684) male federal offenders. The follow-up was eight months for revocations and five years for any/violent recidivism. Indigenous offenders scored significantly higher risk than non-Indigenous offenders on the majority of the indicators (particularly criminal history indicators). Generally, most criminal history indicators and some offence severity indicators predicted revocations, general, and violent recidivism for Indigenous offenders; however, several of the indicators had significantly lower accuracy for Indigenous offenders (particularly criminal history indicators). Overall, Indigenous offenders are a higher risk population and several static risk indicators do not perform as well for this group as for non-Indigenous offenders. Nonetheless, there were numerous static indicators that did predict outcomes for Indigenous offenders. The current findings suggest that it is possible to meaningfully assess static risk for recidivism among Indigenous offenders.  相似文献

Despite the centrality of situational variables to crime theories, they remain uncommon in criminology. Based on the hypotheses drawn from the literature on situational determinants of crime, we examine whether aerial hijackings perpetrated by terrorists are situationally distinct from other aerial hijackings. We define terrorist hijackings as those that include threatened or actual use of illegal force or violence to attain a political, economic, religious or social goal through fear, coercion, or intimidation. Other aerial hijackings include those perpetrated for transportation or extortion purposes. Using a newly updated dataset, we examined 1,019 aerial hijackings that occurred around the world from 1948 to 2007, out of which we classified 122 as terrorism. Results provide strong support for the argument that situational factors measuring organizational resources distinguish terrorist from non-terrorist aerial hijackings, and partial support for the argument that situational factors measuring publicity distinguish these events.  相似文献

The past year has seen a global upsurge of violent attacks by lone, mentally unstable individuals. The motivations for these attacks have varied and extremist ideological drivers are rarely ‘pure’, but mental health problems and personal grievances are common themes. Mentally ill and disenfranchised individuals may be vulnerable to extremist messages and propaganda because such beliefs can be a means of interpreting their social difficulties. Terrorist messages can also be adopted by psychotic people who are seeking to make sense of their symptoms. Most lone-actor attacks are preventable, if there is a system in place for identifying and intervening with antecedent behaviours, which include mental disturbances and the social problems that frequently accompany these conditions. Joint police-mental health models developed to assess and manage fixated persons can be applied to other forms of grievance-fuelled, lone-actor violence. This paper describes the establishment of such a service in Australia, and provides some preliminary data. It also discusses the role of mental health in the current security environment.  相似文献

Assessing an inmate’s risk for recidivism may become more challenging as the length of incarceration increases. Although the population of Long-Term Inmates (LTIs) is burgeoning, no risk assessment tools have been specifically validated for this group. Based on a sample of 1,144 inmates released in a state without parole, we examine the utility of the Level of Service Inventory-Revised (LSI-R) in assessing risk of general and violent felony recidivism for LTIs (n = 555). Results indicate that (a) the LSI-R moderately predicts general, but not necessarily violent, recidivism, and (b) this predictive utility is not moderated by LTI status, and is based in part on ostensibly dynamic risk factors. Implications for informing parole decision-making and risk management for LTIs are discussed.

Abstract

The current study examines sexual and violent reoffence rates for a sample of 2474 sexual offenders over an average of 15 years following release from prison. Reoffence rates are reported as a function of the offenders' victim type and level of risk as assessed by the Automated Sexual Recidivism Scale, a computer scored measure of relevant historical risk factors. Observed sexual recidivism rates for offenders with child victims, adult victims, and mixed victims were quite similar. Results indicate that offenders with exclusively female child victims not only showed a lower rate of sexual reoffending, but that the reoffence rates were relatively low across all levels of actuarial risk. In contrast, those with male child victims and adult victims showed a pronounced escalation of reoffence rates as actuarial risk increased. Results also indicated that adult victim offenders are less consistent in the victim type of their reoffences, with 37% sexually reoffending against child victims. Finally, combined rates of sexual and violent reoffending were particularly high for those with adult victim sexual offence histories. Risk assessment and public policy implications are discussed.  相似文献

Recent research has demonstrated that individual crimes elevate the risk for subsequent crimes nearby, a phenomenon termed “near-repeats.” Yet these assessments only reveal global patterns of event interdependence, ignoring the possibility that individual events may be part of localized bursts of activity, or microcycles. In this study, we propose a method for identifying and analyzing criminal microcycles; groups of events that are proximate to each other in both space and time. We use the Global Terrorism Database (GTD) to analyze over 4,000 terrorist attacks attributed to the FMLN in El Salvador and the ETA in Spain; two terrorist organizations that were both extremely active and violent but differed greatly in terms of history, grievances and motives. Based on the definition developed, we find strong support for the conclusion that many of the terrorist attacks attributed to these two distinctive groups were part of violent microcycles and that the spatio-temporal attack patterns of these two groups exhibit substantial similarities. Our logistic regression analysis shows that for both ETA and the FMLN, compared to other tactics used by terrorists, bombings and non-lethal attacks are more likely to be part of microcycles and that compared to attacks which occur elsewhere, attacks aimed at national or provincial capitals or areas of specific strategic interest to the terrorist organization are more likely to be part of microcycles. Finally, for the FMLN only, compared to other attacks, those on military and government targets were more likely part of microcycles. We argue that these methods could be useful more generally for understanding the situational and temporal distribution of crime.  相似文献

This study clarifies three important issues regarding situational or opportunity theories of victimization: (1) whether engaging in risk activities triggers violent assault during specific, often fleeting moments, (2) how environmental settings along individuals’ daily paths affect their risk of violent assault, and (3) whether situational triggers have differential effects on violent assault during the day versus night. Using an innovative GIS-assisted interview technique, 298 young male violent assault victims in Philadelphia, PA described their activity paths over the course of the day of being assaulted. Case-crossover analyses compared each subject’s exposure status at the time of assault with his own statuses earlier in the day (stratified by daytime and nighttime). Being at an outdoor/public space, conducting unstructured activities, and absence of guardians increase the likelihood of violent victimization at a fine spatial–temporal scale at both daytime and nighttime. Yet, the presence of friends and environmental characteristics have differential effects on violent victimization at daytime versus nighttime. Moreover, individual risk activities appeared to exhibit better predictive performance than did environmental characteristics in our space–time situational analyses. This study demonstrates the value of documenting how individuals navigate their daily activity space, and ultimately advances our understanding of youth violence from a real-time, real-life standpoint.  相似文献

An exhaustive survey of a cohort of forensic patients provided an opportunity for a prospective replication of the predictive accuracy of the Violence Risk Appraisal Guide (VRAG). Data collected during the original survey also permitted a test of the predictive accuracy of clinical assessments of risk on the same cohort. The VRAG yielded a large effect size in predicting violent recidivism (ROC area = .80) over a constant 5-year follow-up and performed significantly better than averaged clinical opinions. The superiority of the VRAG was also observed at very short follow-up times and for very serious violence. Moreover, for 16 subsamples, observed rates of violent recidivism did not differ significantly from the expected rates. VRAG score was unrelated, and clinical judgments inversely related to violent recidivism in the small low-risk sample of female forensic patients. The authors conclude that, regardless of length of opportunity or severity of outcome, actuarial methods are more accurate than is clinical judgment.  相似文献

Although research on terrorism has grown rapidly in recent years, few scholars have applied criminological theories to the analysis of individual‐level political extremism. Instead, researchers focused on radicalization have drawn primarily from political science and psychology and have overwhelmingly concentrated on violent extremists, leaving little variation in the dependent variable. With the use of a newly available data set, we test whether variables derived from prominent criminological theories are helpful in distinguishing between nonviolent and violent extremists. The results show that variables related to social control (lack of stable employment), social learning (radical peers), psychological perspectives (history of mental illness), and criminal record all have significant effects on participation in violent political extremism and are robust across multiple techniques for imputing missing data. At the same time, other common indicators of social control (e.g., education and marital status) and social learning perspectives (e.g., radical family members) were not significant in the multivariate models. We argue that terrorism research would benefit from including criminology insights and by considering political radicalization as a dynamic, evolving process, much as life‐course criminology treats more common forms of crime.  相似文献

Lying behind the recent Counter‐Terrorism and Security Act 2015 is the phenomenon of foreign terrorist fighters which has sparked international and national attention. The 2015 Act deals with many facets of counter terrorism legislation, but its two principal measures are singled out for analysis and critique in this paper. Thus, Part I of the Act seeks to interdict foreign terrorist fighters by preventing suspects from travelling and dealing decisively with those already in the UK who pose a risk. Part V of the Act implements the second, broader aspect, of legislative policy, reflecting the UN emphasis on ‘Countering Violent Extremism’, through the statutory elaboration and enforcement of the ‘Prevent’ element of the long‐established Countering International Terrorism strategy, which aims to stop people becoming terrorists or supporting violent extremism. These measures are explained in their policy contexts and set against criteria of effectiveness, personal freedom, and accountability.  相似文献

The present investigation examined the risk, need, and responsivity (RNR) correlates of MMPI-2 scores in a Canadian sample of 349 federally incarcerated sex offenders, followed up prospectively 19 years post-release. In terms of responsivity indicators, more serious profile patterns were associated with younger age, single marital status, lower education, and lower cognitive ability; the scales generally had weak associations with sex offender treatment completion or change. With respect to criminogenic risk and need, Scales F, 4, 6, 8, and 9 and combinations therein had significant associations with structured measures of sex offender risk, and in turn, consistently predicted sexual or violent recidivism over 5 and 10-year follow-ups. Several of these predictive associations were maintained even after controlling for static and dynamic risk factors. Finally, model based clustering of the MMPI-2 scales generated three clusters termed disordered, emotionally distressed, and predominantly antisocial (non-disordered) subtypes. Although comparatively higher rates of violent recidivism were found with the disordered subtype, this group did not have higher levels of risk and need, broadly speaking, than the other subtypes. The RNR implications of the results are discussed in terms of forensic applications of MMPI-2 with sex offender populations.  相似文献

This study examined whether indicators of compromised police legitimacy explained variations in violent crime within New York City police precincts from 1975 to 1996. Integrating models of urban cultural attenuation and procedural justice, the study hypothesized that variations in patterns of police misconduct and over/under policing (the indicators of police legitimacy) would predict variations in violent crime rates of communities characterized by concentrated structural disadvantage. Using a panel design and controlling for the relevant ecology of crime factors and spatial autocorrelation, the study found that in communities characterized by high disadvantage, incidents of police misconduct predicted variations in violent crime; in communities characterized by extreme disadvantage, both indicators of compromised police legitimacy (misconduct and over policing) predicted variations in violent crime. The study found no significant relationships between the indicators of police legitimacy and violent crime in communities of low disadvantage. Findings support emerging arguments that emphasize the importance of formal institutions of social control in the most structurally disadvantaged communities (that is, those often subjected to cultural attention) and suggest implications for the ecology of crime model and police accountability.  相似文献

Little research has focused on assessing the risk of mentally ill offenders (MIOs) released from state prisons. Here we report findings for 333 mentally ill offenders released from Washington State prisons. Logistic regression identified sets of variables that forecasted felony and violent reconviction as accurately as state-of-the-art risk assessment instruments. Sums of simple recoded versions of these variables predicted reoffense as well as complex logistic regression equations. Five of these 9 variables were found to be relative protective factors. Findings are discussed in terms of the value of stock correctional variables in forecasting risk, the need to base actuarial risk assessments on local data, the importance of protective factors in assessing MIO risk, and the need for dynamic, situational, and clinical variables that can further sharpen predictive accuracy of emergent risk in the community.  相似文献

This article provides an in‐depth assessment of lone actor terrorists’ attack planning and preparation. A codebook of 198 variables related to different aspects of pre‐attack behavior is applied to a sample of 55 lone actor terrorists. Data were drawn from open‐source materials and complemented where possible with primary sources. Most lone actors are not highly lethal or surreptitious attackers. They are generally poor at maintaining operational security, leak their motivations and capabilities in numerous ways, and generally do so months and even years before an attack. Moreover, the “loneness” thought to define this type of terrorism is generally absent; most lone actors uphold social ties that are crucial to their adoption and maintenance of the motivation and capability to commit terrorist violence. The results offer concrete input for those working to detect and prevent this form of terrorism and argue for a re‐evaluation of the “lone actor” concept.  相似文献

This study describes the development of the WAVR‐21, a structured professional judgment guide for the assessment of workplace targeted violence, and presents initial interrater reliability results. The 21‐item instrument codes both static and dynamic risk factors and change, if any, over time. Five critical items or red flag indicators assess violent motives, ideation, intent, weapons skill, and pre‐attack planning. Additional items assess the contribution of mental disorder, negative personality factors, situational factors, and a protective factor. Eleven raters each rated 12 randomly assigned cases from actual files of workplace threat scenarios. Summary interrater reliability correlation coefficients (ICCs) for overall presence of risk factors, risk of violence, and seriousness of the violent act were in the fair to good range, similar to other structured professional judgment instruments. A subgroup of psychologists who were coders produced an ICC of 0.76 for overall presence of risk factors. Some of the individual items had poor reliability for both clinical and statistical reasons. The WAVR‐21 appears to improve the structuring and organizing of empirically based risk‐relevant data and may enhance communication and decision making.  相似文献

Little is known about risk factors for violence among individuals with autism spectrum disorder (ASD). This study uses data from Swedish longitudinal registers for all 422 individuals hospitalized with autistic disorder or Asperger syndrome during 1988-2000 and compares those committing violent or sexual offenses with those who did not. Thirty-one individuals with ASD (7%) were convicted of violent nonsexual crimes and two of sexual offenses. Violent individuals with ASD are more often male and diagnosed with Asperger syndrome rather than autistic disorder. Furthermore, comorbid psychotic and substance use disorders are associated with violent offending. We conclude that violent offending in ASD is related to similar co-occurring psychopathology as previously found among violent individuals without ASD. Although this study does not answer whether ASDs are associated with increased risk of violent offending compared with the general population, careful risk assessment and management may be indicated for some individuals with Asperger syndrome.  相似文献

Abstract

Recent studies indicate that risk for criminal re-offending in identified adult sex offenders may persist decades after the index offence, calling for inquiry into these issues also for younger sex offenders. The author studied temporal patterns for criminal reconvictions and the validity of 16 empirically motivated risk factors for recidivism among all young sex offenders (15–20 years of age) subjected to pre-sentence forensic psychiatric evaluations in Sweden during 1980–1995 (N = 126). The Ss were followed from release and for an average of 115 months. One-hundred-and-seventeen (115 male, 2 female) Ss were available for follow-up with a mean time-at-risk of 80 months. Base rates for sexual and violent non-sexual reconvictions were 30% and 42%, respectively. Using time-at-risk-adjusted hazard ratios derived from Cox regression, characteristics indicative of deviant sexual interest (any previous sex offending behaviour, an index sex offence in a public area, involving a stranger victim, offending on two or more offence occasions, and two or more victims) were found to increase the risk for sexual recidivism. Markers of antisocial lifestyle (early signs of DSM-IV Conduct Disorder and any prior violent conviction), sex offence-related characteristics indicating aggression proneness (use of threats or force and physical victim injury), and victim penetration, increased the risk for violent non-sexual reconvictions. Survival analyses indicated that the rate of sexual reconvictions as a function of time at risk decreased distinctly after 6–7 years whereas the rate for violent non-sexual reconvictions remained largely the same.  相似文献
