text: On April 6, 1932, Nationalist partisans marched into the Capitol building in San Juan to protest a legislative proposal to establish the current Puerto Rican flag as the official flag of the insular government. Nationalists preferred the flag used during the Grito de Lares. A melée ensued in the building, and one partisan fell to his death from a second floor interior balcony.  The protest was condemned by the legislators Rafael Martínez Nadal and Santiago Iglesias; and endorsed by others, including the future leader of the statehood party, Manuel García Méndez.
  On October 24, 1935, a confrontation with police at University of Puerto Rico campus in Río Piedras resulted in the deaths of 4 Nationalist partisans and one policeman. The event is known as the Río Piedras massacre. This and other events led the party to announce on December 12, 1935, a boycott of all elections held while Puerto Rico remained part of the United States.
  On February 23, 1936, in San Juan, two Nationalists assassinated the Insular Police Chief and ex-U.S. Marine officer, E. Francis Riggs. The Nationalist perpetrators, Hiram Rosado and Elías Beauchamp, were arrested, transported to police headquarters, and killed within hours without trial. No policeman was ever tried or indicted for their deaths.
