Abstract Purpose In 2018, the US Marshals Service (USMS) and local law enforcement implemented “Operation Triple Beam” (OTB) in and around Houston, TX. While OTB has been touted as an exemplary initiative, its impact on offending and co-offending remains a mystery. Using over a decade of web-scraped arrest data from 16 law enforcement agencies I evaluate the impact of OTB on co-offending network involvement in Galveston County, TX. Methods Difference-in-difference regression analysis is employed to assess change in centrality from the co-offending network preceding OTB to the network following OTB, relative to change over similarly structured networks in a randomly sampled control group drawn from the 7 years preceding OTB. Results Arrest during OTB, to a greater extent than arrest during counterfactual periods, is associated with reductions in co-offending network involvement. The greatest reductions are observed in harmonic closeness and betweenness centrality. Further, OTB arrestees appear to have held co-offending network positions of greater prestige (eigenvector) when compared with the control group. Conclusions Consistent with its goals, OTB appears to have targeted prominent offenders within the regional co-offending network. OTB appears to have been especially effective at damaging the involvement of the networks' brokers.

全县共犯网络中的帮派打击和罪犯中心化：三光束行动的网络评估

摘要 目的 2018 年，美国法警局 (USMS) 和当地执法部门在德克萨斯州休斯顿及其周边地区实施了“三光束行动”(OTB)。虽然 OTB 被吹捧为模范举措，但它对犯罪和共同犯罪的影响仍然是个谜。我使用来自 16 个执法机构的十多年网络抓取的逮捕数据评估了 OTB 对德克萨斯州加尔维斯顿县共同犯罪网络参与的影响。方法 使用差异回归分析来评估从 OTB 之前的共同犯罪网络到 OTB 之后的网络的中心性变化，相对于从 OTB 之前的 7 年中抽取的随机抽样对照组中类似结构网络的变化。结果 OTB 期间的逮捕，比反事实期间的逮捕更大，与减少共同犯罪网络的参与有关。在和谐接近度和中介中心性方面观察到最大的减少。此外，与对照组相比，OTB 被捕者似乎拥有更高声望（特征向量）的共同犯罪网络职位。结论 与其目标一致，OTB 似乎针对区域共同犯罪网络中的突出罪犯。OTB 似乎在破坏网络经纪人的参与方面特别有效。OTB 似乎针对区域共同犯罪网络中的突出罪犯。OTB 似乎在破坏网络经纪人的参与方面特别有效。OTB 似乎针对区域共同犯罪网络中的突出罪犯。OTB 似乎在破坏网络经纪人的参与方面特别有效。
