On August 29, 1970, 20,000 to 30,000 people from across the country joined to march and protest against the Vietnam War. The marchers rallied at Laguna Park (present-day Ruben Salazar Park). The event was organized by the Chicano Moratorium, an alliance of Chicano anti-war activists. It called attention to the disproportionate number of young Latino casualties in the war. At the time, 19 percent of U.S. war casualties bore Spanish surnames, despite Latinos being only 12 percent of America’s population.
The rally at Laguna Park was peaceful and even festive, featuring speakers, musicians, dancers and theatrical performers. The crowd included families with children. A few hours after the rally started, sheriff deputies responded to call from a liquor store near the park that several youths had stolen beverages. As deputies entered the area, they were pelted from the fringes of the crowd. Police reinforcements were already poised, so deputies formed skirmish lines to push back against the rally. The rally was declared an illegal assembly. Many in the rally were still unaware of what of was happening at its fringes, when deputies fired tear gas into the park. Baton-swinging police skirmish lines followed to clear the park. People fled where they could to escape the gas and batons. Some, enraged by the police excesses, fought back. Others smashed and torched businesses along Whittier Boulevard and chased off firefighters.
Ruben Salazar, a popular award-winning Mexican American journalist, took refuge with others in a nearby bar. He was killed when a deputy fired a tear gas canister through the bar’s open door.
By early evening, 44 businesses had been looted or destroyed, hundreds arrested, 75 law enforcement officers and many others injured and three, including Salazar, were dead. The day became a historic Latino civil rights event, but, as is so common in the struggle for civil rights and social justice, one not without pain and loss.
