Answer: No.
Why?
Frank case not only was a miscarriage of justice but also symbolized many of the South's fears at that time. Workers resented being exploited by northern factory owners who had come south to reorganize a declining agrarian economy. Frank's Jewish identity compounded southern resentment toward him, as latent anti-Semitic sentiments, inflamed by Tom Watson, became more pronounced. Editorials and commentaries in newspapers all over the United States supporting a new trial for Frank and/or claiming his innocence reinforced the beliefs of many outraged Georgians, who saw in them the attempt of Jews to use their money and influence to undermine justice.
The pardon was motivated in part by the 1982 testimony of eighty-three-year-old Alonzo Mann, who as an office boy had seen Jim Conley carrying Mary Phagan's body to the basement on the day of her death. Conley had threatened to kill Mann if he said anything, and the boy's mother advised him to keep silent. For those who thought Frank innocent, this provided confirmation; for those who believed him guilty, this was insufficient evidence to change their views.
In 1986 the Georgia State Board of Pardons and Paroles pardoned Frank, stating:
Without attempting to address the question of guilt or innocence, and in recognition of the State's failure to protect the person of Leo M. Frank and thereby preserve his opportunity for continued legal appeal of his conviction, and in recognition of the State's failure to bring his killers to justice, and as an effort to heal old wounds, the State Board of Pardons and Paroles, in compliance with its Constitutional and statutory authority, hereby grants to Leo M. Frank a Pardon.
