Because Chicanos had the highest number of causalities in proportion to their participation, many Chicano activists opposed the Vietnam War. On August 29, 1970 a group of Chicano activists and concerned citizens staged a rally and march on Whittier Boulevard in the Boyle Heights neighborhood of Los Angeles. The event and the resulting movement grew out of meetings that began in 1969 with Chicano Moratorium rally organized by the Brown Berets (a group of young Chicano revolutionaries). Although the event organizers urged non-violence, police officers and others began to attack the crowd as they marched. Three deaths resulted, including that of Los Angeles Times reporter Ruben Salazar. This flier advertises a 1971 march in response to the events of the previous year. Journalist Frank del Olmo collected this flier and other information like it to help in the background research of his newspaper articles. Frank del Olmo was born in Los Angeles, California on May 18, 1948. After graduating from the University of California, Los Angeles (UCLA), del Olmo entered California State University, Northridge (CSUN) to study journalism. He joined the staff of the Los Angeles Times in 1971, and served as its associate editor until his death in 2004. 13.9 in. x 8.4 in.
