On Feb. 26, 1931, a sunny Sunday in Los Angeles, hundreds gathered for an afternoon of relaxation in La Placita park in the heart of the city’s Mexican community.
Suddenly, a large group of plainclothes officers armed with guns and batons entered the park. Two officers were posted at each entrance to La Placita so that no one could leave. Dozens of flatbed trucks circled the park’s perimeter.
Officers rounded up all the people with brown skin, said Joseph Dunn, a former Democratic state senator from California, who researched this forgotten episode of U.S. history.
