text: The San Juan Nationalist revolt was a Nationalist attempt to enter the Governor's mansion, La Fortaleza, in order to attack then-governor Luis Muñoz Marín. The hour-long shootout resulted in the death of four Nationalists: Domingo Hiraldo Resto, Carlos Hiraldo Resto, Manuel Torres Medina and Raimundo Díaz Pacheco. Three guards were also seriously wounded.
  Various other shootouts took place throughout island – including those at Mayagüez, Naranjito, Arecibo, and Ponce, where Antonio Alicea, Jose Miguel Alicea, Francisco Campos (Albizu Campos's nephew), Osvaldo Perez Martinez and Ramon Pedrosa Rivera were arrested and accused of the murder of police corporal Aurelio Miranda during the revolt. Raul de Jesus was accused of violating the Insular Firearms Law.
  On October 31, police officers and National Guardsmen surrounded Salón Boricua, a barbershop in Santurce. Believing that a group of Nationalists were inside the shop, they opened fire. The only person in the shop was Campos barber Vidal Santiago Díaz. Santiago Díaz, who fought alone against the attackers for three hours, received five wounds, including one in the head. The battle was transmitted "live" via the radio airwaves to the public in general.
  On November 1, 1950, Griselio Torresola and Oscar Collazo unsuccessfully attempted to assassinate U.S. President Harry S. Truman, who was staying at the Blair House in Washington, D.C.
  Truman supported development of a constitution for Puerto Rico and the 1952 status referendum on it; 82% of the voters approved the constitution. The US Congress also approved the constitution.
