Amid growing civil unrest, President José Figueroa Alcorta appointed Falcón as Chief of the Argentine Federal Police upon taking office in 1906.
Falcón initiated dialogue with strike organizers, who were mainly women and whose demands centered around rising rents and deteriorating conditions in the city's estimated 2,000 tenements.
FORA and the Socialist UGT were granted an audience with the President of the Argentine Senate, Benito Villanueva, and obtained the commutation of lengthy prison sentences for those arrested (which per municipal statutes carried a term of triple that of similar offenses not committed in the context of a protest).
They demanded that Falcón resign, though he refused to do so; members of the Buenos Aires Stock Exchange led a rally in his support as President Figueroa Alcorta commended him for his efforts.
