This is a complex question that requires a long and detailed explanation to fully address all of its nuances. However, I'll provide a brief summary to give you a clear overview. If you'd like to dive deeper into any specific aspect or discuss it further, I'd be happy to do so!
The Sacco and Vanzetti case is now seen as a significant miscarriage of justice, largely shaped by nativism and anti-immigrant attitudes.

This trial stands as a crucial example in American history of how prejudice can undermine fairness in the legal system.
