Answer: the two men needed better legal representation.
The conclusion of the Sacco and Vanzetti case suggested that the two men needed better legal representation. Sacco and Vanzetti earned a guilty verdict under unclear circumstances like the money was not found with them and they don't have previous criminal record. For long years, the pistol that was with Sacco was not verified to be the murder weapon however, in the recent years due to the advancement of technology it was proven that it was indeed the murder weapon. Many assumed that Sacco is guilty and Vanzetti was innocent. If they were only represented by better legal counsels they would not have been executed.
