A massive security operation, involving 22,000 police and gendarmerie officers nationwide—with 8,000 concentrated in the Paris metropolitan area—had been meticulously planned. This extraordinary deployment was in anticipation of potential celebrations or disappointments surrounding the Paris Saint-Germain’s performance in the Champions League final on Saturday, May 30, evening. However, even before the match concluded, early confrontations had already begun. By the afternoon, as approximately 20,000 fans gathered at the Parc des Princes to watch the broadcast, initial clashes between law enforcement and so-called “supporters” near the stadium resulted in 20 arrests, foreshadowing the unrest that would follow.
