March 1954 - Four Puerto Rican freedom fighters opened fire at US congressmen, from the visitors gallery at the US Capitol, as part of their campaign to free Puerto Rico from US colonialism and make it a sovereign nation once more.
The nationalists, identified as Lolita Lebrón, Rafael Cancel Miranda, Andres Figueroa Cordero, and Irving Flores Rodríguez, unfurled a Puerto Rican flag and began shooting at the 240 Representatives of the 83rd Congress, who were debating an immigration bill. Five Representatives were wounded, one seriously, but all recovered. The assailants were arrested, tried and convicted in federal court, and given long sentences, effectively life imprisonment. In 1978 and 1979, they were pardoned by President Jimmy Carter; all four returned to Puerto Rico. [video]/[video]
