"Someone, it is now admitted, blundered in the handling of the throng of Hunger Marchers that sought to present petitions at the Ford plant in River Rouge." The newspaper continued that 'The killing of obscure workmen, innocent of crime" was "a blow directed at the very heart of American institutions." The Detroit News reported that "Insofar as the demonstration itself had leaders present in the march, they appear to have warned the participants against a fight." The mainstream trade union movement spoke out against the killings. The Detroit Federation of Labor, affiliated with the American Federation of Labor, issued a statement saying that "The outrageous murdering of workers at the Ford Motor Plant in Dearborn on Monday has cast a stain on this community that will remain a disgrace for many years." On March 12, at least 25,000 and perhaps as many as 60,000 people participated in a funeral procession for the four dead marchers, who were buried side by side in Woodmere Cemetery in Detroit. The slogan of the funeral march was "Smash the Ford-Murphy Terror". Detroit Mayor Frank Murphy said that "the chaining of patient prisoners to beds is a brutal practice that should find no encouragement in an enlightened hospital".

Murphy denounced Harry Bennett as an "inhuman brute" and called Henry Ford a "terrible man". He asked, "What is the difference between the official Dearborn police and Ford's guards?" His answer was, "A legalistic one." A fifth marcher, Curtis Williams, did not succumb to his injuries for three months. When Williams, an African American, died from his injuries, Woodmere Cemetery did not allow him to be buried there under its "whites only" policy of segregation. Curtis Williams' family arranged for his cremation, and his ashes were scattered in the area near the graves of his fellow marchers. Nine years later, on April 11, 1941, after the economy had begun to recover and 40,000 Ford workers conducted a ten-day sit down strike, Henry Ford signed a collective bargaining agreement with the United Auto Workers union. Grand Jury report Prosecutor Harry S. Toy convened a grand jury to investigate the violence. At the end of June, they completed their investigation and issued their report. They said "After hearing many witnesses
