the sensational july 1916 preparedness day bombing of the san francisco preparedness day parade — a terrorist attack which killed 8 and wounded more than 40 others — took place while berkman was already publishing "the blast" in that same city. the editorial location of the semi-monthly anarchist magazine combined with its inflammatory name proved irresistible to local authorities, who raided the paper's offices on july 29, 1916 without a search warrant. no evidence was located on the premises and there were no arrests made.
