The I. W. W. found an excuse for their riotous action in the refusal of communities to permit them to speak in the streets and public places. This, they claimed, was an invasion of their constitutional right of free speech. The experience of San Diego serves as an example of their "free speech" campaigns. In 1910, I. W. W. agitators began to hold public meetings in the streets, in the course of which their language increased in ferocity until the indignation of the community was aroused. An ordinance was then passed by the city council prohibiting street speaking within the congested portions of the city, but allowing street meetings in other parts of the city if a permit from the police department were first obtained. There was, however, no law requiring the issue of such a permit, and none was granted to the agitators. This restriction of their liberties greatly incensed the agitators, who at once raised the cry of "free speech" and began to hold meetings in defiance of the ordinance. The jail was soon glutted with these apostles of riotous speaking. In order to delay the dispatch of the court's overcrowded calendar, every one demanded a jury trial. The mayor of the town then received a telegram from the general secretary of the organization which disclosed their tactics: "This fight will be continued until free speech is established in San Diego if it takes twenty thousand members and twenty years to do so." The national membership of the I. W. W. had been drafted as an invading army, to be a constant irritation to the city until it surrendered. The police asserted that "there are bodies of men leaving all parts of the country for San Diego" for the purpose of defying the city authorities and overwhelming its municipal machinery. A committee of vigilantes armed with "revolvers, knives, night-sticks, black jacks, and black snakes," supported by the local press and commercial bodies, undertook to run the unwelcome guests out of town. That this was not done gently is clearly disclosed by subsequent official evidence. Culprits were loaded into auto trucks at night, taken to the county line, made to kiss the flag, sing the national anthem, run the gauntlet between rows of vigilantes provided with cudgels and, after thus proving their patriotism under duress, were told never to return. "There is an unwritten law," one of the local papers at this time remarked, "that permits a citizen to avenge his outraged honor. There is an unwritten law that permits a community to defend itself by any means in its power, lawful or unlawful, against any evil which the operation of the written law is inadequate to oppose or must oppose by slow, tedious, and unnecessarily expensive proceeding." So this municipal homeopathy of curing lawlessness with lawlessness received public sanction.
