How did Sacco and Vanzetti change America?

I have been doing some research on Sacco and Vanzetti, and their trial, but I have been unable to find any significant impact that they left on the USA. While their death may have resulted in several bombings, protests, and books, did they change anything in the government or in how cases were dealt with? Thanks!How did Sacco and Vanzetti change America?Their supporters started a mass counter culture in the 1920s with anarchy. It began the first worldwide protests over the trial. The outcome of the trial was the first time people realized corruption in American government and court systems against immigrants, and it was the first time people demonstrated their disapproval of the government.
