Illegitimate police violence, collusion, corruption and impunity at different levels are not entirely new phenomena in Argentina. As the lingering effects of the country’s dictatorial past, they are inextricably linked to the training of the Argentine police and military during the Cold War effected as part of anti-Communist campaigns (for example, through Operation Condor); to a long-ingrained understanding of low-income neighbourhoods as territories of exception when it comes to law enforcement; and to the state terrorism perpetrated by the last dictatorship. Overall, by looking at collusion from the vantage point of fine-grained material, The Ambivalent State offers an impressive contribution to understanding the ambiguous illicit practices of the state in marginalised urban space in the eyes of its most vulnerable actors in Argentina.
