Today in Labor History March 21, 1937: Palm Sunday, cops killed 19 unarmed men, women and children marching in a protest in Ponce, Puerto Rico. They injured another 200 civilians. The Puerto Rican Nationalist Party organized the march to commemorate the abolition of slavery in 1873 and to protest the imprisonment of the party’s leaders by the U.S. The police used Thompson submachine guns, rifles and pistols, shooting marchers in the back, during the Ponce Massacre. A commission placed the blame for the massacre on the U.S. appointed governor of Puerto Rico, Blanton Winship. However, no one, including Winship, nor any of the shooters, were ever prosecuted or punished.
