Insufficient supply chain management expertise among law enforcement departments during black swan events may hurt the operationality, functionality, and effectiveness of their goal to keep the communities safe. Grounded in black swan theory, the purpose of this multiple case study was to explore strategies for building supply chain resilience and sustainability within law enforcement. Data were collected from 11 command staff personnel from three law enforcement departments in South Carolina through semi-structured interviews, member checking, and assessments of organizational documents related to departmental supply chain policies and procedures. Data were analyzed using Braun and Clarke’s six-step thematic analysis framework. Six key themes emerged from the thematic analysis: (a) implementing agile strategies for supply resilience, (b) adjusting policies to ensure timely supplies, (c) utilizing diverse suppliers for adaptable procurement, (d) using diverse funding avenues for agile procurement, (e) enhancing communication for the dynamic supply chain, and (f) strategic engagement and proactive resource planning. The key recommendation for action is for command personnel to establish, implement, and integrate effective agile strategies, processes and protocols, and seek alternative funding sources of funding such as state, local, and federal grants to anticipate and mitigate the adverse effects of Black Swan events on their supply chains. The implications for positive social change include the potential for law enforcement agencies to operate more efficiently, thereby rendering more efficient policing and community safety services even during disrupting events like a pandemic.
