What was the outcome in the Nicola Sacco and Bartolomeo Vanzetti Trial?

Nicola Sacco and Bartolomeo Vanzetti were convicted of murder in 1921, despite widespread protests regarding the fairness of their trial. The outcome was heavily criticized for perceived anti-immigrant and anti-anarchist bias, leading to a global outcry. Their execution by electric chair occurred in 1927, but many continued to believe in their innocence. In 1977, Massachusetts Governor Michael Dukakis formally declared them innocent, acknowledging the flaws in the trial.
