The number of jurisdictions implementing focused deterrence strategies targeted at gangs continues unabated. Although recent research suggests positive impacts of the strategy on reductions in gun violence, little is known about the particular mechanisms operating behind the strategy. This article provides a descriptive analysis of the law enforcement activities or levers undertaken after enforcement operations in Philadelphia as a part of the focused deterrence strategy. The article quantifies the execution of levers related to arrest, case processing, and probation sanctioning during enforcement activities after shootings. The results show that Philadelphia achieved success in implementing the enforcement levers as intended, and there was little evidence that arrest practices were overly aggressive. The authors suggest that future evaluations seek to carefully document the wide array of levers used in concert with an assessment of community understanding of and reactions to the strategy as well as an examination of reactions of group members targeted.

费城团体暴力干预的执法活动：逮捕，案件处理和缓刑审查

实施针对团伙的威慑战略的辖区数量仍在增加。尽管最近的研究表明该策略对减少枪支暴力有积极影响，但对该策略背后的特定机制知之甚少。本文将对在费城执法行动后开展的执法活动或执法手段进行描述性分析，以此作为重点威慑战略的一部分。该文章量化了枪击事件发生后执法活动中与逮捕，案件处理和缓刑制裁有关的杠杆的执行情况。结果表明，费城在按计划实施执法手段方面取得了成功，几乎没有证据表明逮捕行为过于激进。
