Final answer:
Nicola Sacco and Bartolomeo Vanzetti were wanted for a robbery and double homicide in 1920, with their trial highlighting nativism and bias in the American justice system during the Red Scare.
Step-by-step explanation:
Nicola Sacco and Bartolomeo Vanzetti were Italian immigrants and anarchists who were controversially accused and convicted of a robbery and double homicide that took place at a factory in Massachusetts in 1920. The crime they were wanted for was linked to their radical political beliefs during a period known as the Red Scare, where fear of left-wing ideologies and foreigners was pervasive.
Despite appeals and global protests suggesting a miscarriage of justice, Sacco and Vanzetti were executed in 1927, with their trial highlighting the era's intense nativism and the American criminal justice system's potential bias against immigrants and radicals.
