During the years 2024 and 2025, several members of the National Police Corps (CNP) were discovered while performing undercover work as infiltrators in social movements in Catalonia. Catalan society reacted with incomprehension and astonishment to a practice that seemed structural and was apparently not framed within any criminal investigation. The whole situation smelled of mothballs and showed a certain apathy regarding the bad image of the police force among Catalan social movements.Surprisingly (or perhaps not so much), the ministry did not correct or dismiss anyone. Only a statement of support and the renewal of their confidence in the police.May 2026. Two female police officers hide their identity and participate in a teaching staff assembly, posing as teachers. This action by the Mossos d’Esquadra in an assembly of the education sector is a fact that is difficult to explain. It is an inopportune, disproportionate, and poorly executed initiative, and in turn, it has organizational and social consequences that are so easily predictable that they prevent a minimally rational understanding of the decision-making by those responsible. Despite the differences with the previous case of the CNP, it seems that instead of learning from the mistakes of others to consolidate a different model, what the Government has done is precisely to take the mistake as a model.The educational community is not a problem for the security of Catalonia and its activism in protest constitutes a right. Furthermore, their recent mobilizations have been free of incidents. On the other hand, the mediation units of the Mossos d’Esquadra have (or had, perhaps) a direct line with the unions and can forward demands, collect proposals, and establish measures to make their right to protest compatible with the free movement of the rest of the citizens. There is absolutely nothing to suggest that such an intrusive measure as infiltration in a protest context like the current one is necessary. This represents not only bad practice but also a change in a consolidated model, which denigrates the proximity work and conflict management of a modern force of which some of us were proud.
