Marshall held another press conference on October 17 to announce that the NAACP was requesting a formal government investigation into the working conditions that had led the men to strike. He called attention to three aspects: the Navy policy that put the great majority of African Americans into segregated shore duty, the unsafe munitions handling practices and lack of training that had led to the catastrophic detonationand the unfair manner in which 50 of 258 men had been singled out as mutineers. when their actions concerning loading ammunition after the explosion were not significantly different from the other 208 men. Marshall pointed to the men of Division One who had refused to load ammunition prior to August 9, but had been shipped out and given other duty, not arrested and court-martialed.
