In 1911, the American Federation of Labor (AFL) called on Darrow to defend the McNamara brothers, John and James, who were charged in the Los Angeles "Times" bombing on October 1, 1910, during the bitter struggle over the open shop in Southern California. The bomb had been placed in an alley behind the building, and although the explosion itself did not bring the building down, it ignited nearby ink barrels and natural gas main lines. In the ensuing fire, 20 people were killed. The AFL appealed to local, state, regional and national unions to donate 25 cents per capita to the defense fund, and set up defense committees in larger cities throughout the nation to accept donations.
