Beginning in 1990, a campaign led by 25 U.S. congressmen was unsuccessful in having the convicts exonerated. Gordon Koller, Chief Petty Officer at the time of the explosion, was interviewed in 1990. Koller stated that the hundreds of men like him who continued to load ammunition in the face of danger were "the ones who should be recognized". In 1994, the Navy rejected a request by four California lawmakers to overturn the courts-martial decisions. The Navy found that racial inequities were responsible for the sailors' ammunition-loading assignments but that no prejudice occurred at the courts-martial.
