Nicola Sacco and Bartolomeo Vanzetti were Italian immigrants who were – controversially – convicted of murdering Alessandro Berardelli and Frederick Parmenter, a security guard and a payroll clerk, during an armed robbery of the Slater and Morrill Shoe Company in Massachusetts. About a century has passed and experts -- and armchair experts, too! – continue to debate this case, but not whether they did or didn't do it. They continue to debate one very big thing: whether or not Sacco and Vanzetti received a fair trial.
