Starting in 2014, Brazilian politics was shaken up by the lava jato (LJ) operation, a law‐centered anticorruption initiative. LJ unveiled a large corruption scheme in Brazil's national oil company Petrobras, which involved Petrobras directors, political party officials, and large construction companies. LJ was both disruptive and contentious. To some, it started a new chapter in Brazilian history, marked by greater respect for the “rule of law” and a collective “state of mind” concerned with “ending impunity” and building integrity in politics and businesses. To others, it contributed to undermining democracy and the rule of law, paving the way for an autocratic leader—the current Brazilian president Jair Bolsonaro. This article sheds further light on those discussions by looking at LJ as a site of “legal consciousness” production. Empirically, the article focuses on conversations generated by lead LJ prosecutors on a major social media platform (Facebook) from 2017 to 2019. Considering this body of data, the article addresses the question: “When prosecutors and ‘the people’ talked about LJ, what did they talk about?” My findings support the more skeptical views of the operation. The exchanges between LJ prosecutors and their Facebook followers supported the co‐production of a cultural schema averse to the “rule of law.” These findings have implications for both legal consciousness and anticorruption research.
