Understanding modern terror and insurgency through the lens of street gangs: ISIS as a case study

Matthew Valasik; Matthew D. Phillips

Purpose The purpose of this paper is to use nearly a century’s worth of gang research to inform us about modern terrorist groups, specifically the Islamic State of Iraq and Syria (ISIS). Design/methodology/approach A case study approach is employed, comparing and contrasting the competing theoretical frameworks of gangs and terrorist organisations to understand group structure, demographics, patterns of behaviour (e.g. territoriality, strategic, and instrumental violence), goals, and membership patterns of ISIS. Findings The qualitative differences of ISIS make them more comparable to street gangs than other terrorist groups. Practical implications ISIS, while being qualitatively different from other terrorist groups, actually has many similarities with street gangs allowing for the adaptation of effective gang prevention, intervention, and suppression strategies. This paper highlights how the expansive literature on street gangs is able to inform practical interventions to directly target ISIS and deradicalise potential recruits. By introducing a gang-terror nexus on the crime-terror continuum, this paper provides a useful perspective on the decentralised but dynamic nature of modern era insurgencies. This paper urges similar case studies of terrorist organisations to determine the extent to which they conform to street gang characteristics. Originality/value Terrorist groups are often compared to street gangs, yet it has not been until the last few years that gang researchers (Curry, 2011; Decker and Pyrooz, 2011, 2015a, b) have begun to compare and contrast these two deviant group archetypes. The goal of this paper is to use nearly a hundred years of gang research to better equip scholars and practitioners with a broader understanding of terrorism and insurgency in the era of globalisation by presenting a case study of ISIS using a street gang perspective.

Barriocide: Investigating the Temporal and Spatial Influence of Neighborhood Structural Characteristics on Gang and Non-Gang Homicides in East Los Angeles:

Matthew Valasik; Michael S. Barton; Shannon E. Reid; George E. Tita

This study explored how changes in neighborhood structural characteristics predicted variation in gang versus non-gang homicides in a policing division of the Los Angeles Police Department (LAPD). Longitudinal negative binomial models were examined to test the relationship between-neighborhood structural covariates with gang and non-gang homicides over a 35-year period. This study highlights the potential to estimate temporal effects not captured by cross-sectional analyses alone. The results underscore a unique feature that distinguishes gang homicides from other forms of non-gang violence, its tenacious clustering, and spatial dependence over time.

Does Predictive Policing Lead to Biased Arrests? Results From a Randomized Controlled Trial

P. Jeffrey Brantingham; Matthew Valasik; George Mohler

ABSTRACT Racial bias in predictive policing algorithms has been the focus of a number of recent news articles, statements of concern by several national organizations (e.g., the ACLU and NAACP), and simulation-based research. There is reasonable concern that predictive algorithms encourage directed police patrols to target minority communities with discriminatory consequences for minority individuals. However, to date there have been no empirical studies on the bias of predictive algorithms used for police patrol. Here, we test for such biases using arrest data from the Los Angeles predictive policing experiments. We find that there were no significant differences in the proportion of arrests by racial-ethnic group between control and treatment conditions. We find that the total numbers of arrests at the division level declined or remained unchanged during predictive policing deployments. Arrests were numerically higher at the algorithmically predicted locations. When adjusted for the higher overall crime rate at algorithmically predicted locations, however, arrests were lower or unchanged.

Ctrl+ALT-RIGHT: reinterpreting our knowledge of white supremacy groups through the lens of street gangs

Shannon E. Reid; Matthew Valasik

ABSTRACT For the last 30 years, gang scholars have explicitly disregarded white youth who are active in groups with overt or implicit ties to neo-Nazi/skinhead or white power ideologies from street gang research. This article argues that this decision to keep these two groups separate stems from a misinterpretation of the realities of these groups and this decision has had a long-standing impact on how researchers, law enforcement and policymakers understand and interact with youth active in these groups. The coining of the term ‘Alt-Right,’ and the re-emergence of white power youth in the international dialogue, underscores how the lack of systematic research severely limits our knowledge about youth involved in gangs with white power leanings. Based on these concerns, this article challenges the current understanding of both skinheads and their troublesome youth groups/gangs. By orienting the limited research on skinhead gangs within key street gang domains, this article draws attention to disconnects in the literature that have influenced how researchers approach the study of skinhead youth. This study’s conclusions support the purposeful inclusion of skinhead youth in future street gang research.

The George Wilson Effect: Does Intergenerational Closure and Collective Efficacy Reduce Juvenile Delinquency in a Neighborhood?

Matthew Valasik; Michael S. Barton

ABSTRACT A substantial amount of research found crime and delinquency to be lower in areas with stronger neighborhood communities, but the casual mechanism behind this association remains debated. The current study contributes to this debate by examining the association of two forms of social capital with rates of delinquency. The first, collective efficacy, has been widely studied, while the second, intergenerational closure has not. While the results support previous research indicating the primary role of collective efficacy as a proactive factor against delinquency, results for intergenerational closure suggest the influence of neighborhood community on delinquency does not always result in lower delinquency.

CRASH and burn: abatement of a specialised gang unit

Matthew Valasik; Shannon E. Reid; Matthew D. Phillips

Purpose – The purpose of this paper is to examine the impact of the temporary disbandment of a gang unit on collecting gang intelligence and arresting gang members in one of the Los Angeles Police Department’s Community Policing Areas. Design/methodology/approach – An interrupted time series methodology (ARIMA) is utilised to examine 1,429 field interview cards and 1,174 arrests of gang members that occurred from 1 January 2010 to 31 December 2011 within one police division. Findings – Results indicated that the dismantling of the gang unit negatively impacted the collection of intelligence on gang members by officers, regardless of whether the officers were officially serving in the gang unit. Suppression efforts by gang unit officers also resulted in a sustained decline. Originality/value – Given that many urban centres have specialised gang units, this study demonstrates how organisational turnover or disbandment of a gang unit negatively impacts a department’s ability to deal with local gang issues. Furthermore, these finding suggest that police organisations should consider such ramifications on intelligence-based policing activities.

Exploring the Influence of Hookup Culture on Female and Male Rape Myths

Timothy T. Reling; Sarah Becker; Leah Drakeford; Matthew Valasik

The present study systematically assesses the influence of hookup culture endorsement on the acceptance of female rape myths (i.e., false, stereotypical, or prejudicial beliefs regarding sexual assault involving female survivors) and male rape myths (i.e., false, stereotypical, or prejudicial beliefs about sexual assault involving male survivors). Multivariate regression analyses were conducted to assess the primary hypotheses that a particular form of hookup culture endorsement (i.e., the belief that hookups elevate an individuals social status) would act as the primary predictor of male and female rape myth acceptance among a sample of 376 U.S. college students. As with prior research, a complex relationship emerged for both male and female rape mythology in which acceptance increases or decreases based upon the form of hookup culture endorsement examined, as the endorsement of beliefs reflecting heterosexual power dynamics (e.g., harmlessness and status attainment) functioned as positive predictors of rape myth acceptance, while beliefs challenging such assumptions (e.g., sexual freedom) served to decrease rape myth acceptance. Results supported the primary hypotheses that beliefs concerning hookups and status attainment would be the largest predictor of male rape myth acceptance and female rape myth acceptance. Consistent with prior research, the predictive power of gender and religiosity was initially significant across both male and female rape myth acceptance yet diminished when controlling for levels of hookup culture endorsement. Furthermore, analyses indicated gender differences among the influences of hookup culture endorsement for female rape myth acceptance alone, as even though beliefs concerning status served as an aggravating factor for female rape myth acceptance, beliefs concerning sexual freedom served as a mitigating factor for women only.

The Schrödinger’s Cat of Gang Groups: Can Street Gangs Inform Our Comprehension of Skinheads and Alt-Right Groups?

Matthew Valasik; Shannon E. Reid

ABSTRACT Given the current political climate, the mainstreaming of Alt-Right groups, and growing public concern, this paper argues that gang scholars are well situated to investigate these Alt-Right groups and their members. Qualitative and quantitative data collected from youth incarcerated within California’s Division of Juvenile Justice are used to examine the differences and similarities between a range of individual-level risk factors and group-level descriptors to better understand the overlap between members of racist skinhead/Alt-Right groups and street gangs. Findings highlight how closely aligned these two groups are across domains.
