The bomb that shook San Francisco

Over a century ago, tensions about the war in Europe, labor unrest and the Committee for Law and Order exploded. Quite literally on July 22, 1916, a suitcase bomb killed 10 and seriously injured 40, at the city’s “Preparedness Day” parade—one of the largest parades in the city’s history with 51,000 marchers participating. Everybody seemed to be there including Phoebe Hearst leading delegations of women down Market street. The bomb exploded at 2:06 at Market and Steuart Streets. 
   The idea behind a “preparedness” demonstration, which also took place in New York and Washington, D.C, was to support the American military in the event of the nation entering World War I - which we did one year later. But many were against this interference overseas, and labor leaders protested it was another get rich scheme for industrialists on the backs of working men.  So after the mystery bomb blast left little evidence, the police and government was eager to find the criminals. Immediately socialists, anarchists and pro-labor organizers were targeted. Two labor activists, whom the papers referred to as "radicals", were convicted and jailed then released in 1939 after the police were accused of witness tampering in a mob scene trial.  ​
