In 2021, I got my hands on a massive NYPD complaint dataset from Gothamist/WNYC and immediately went down a data rabbit hole. Built a network of 29,915 officer nodes with 159,671 relationships using Neo4j and Gephi (love-hate relationship with Gephi, but unrivaled for networks).
When Gothamist reporter George Joseph interviewed victims, they confirmed what the network showed - certain officers were "catalysts" who other officers "followed" into misconduct. Math and reality matched up! I documented everything in excruciating detail so others could replicate it for their own police departments.
