The case of Sacco and Vanzetti involved Italian immigrants and anarchists charged with robbery and murder during the 1920s, leading to their controversial executions and highlighting issues of bias and justice system fairness.
Explanation:
The case of Sacco and Vanzetti was similar to that of individuals arrested during the Palmer Raids of 1919 in that both involved radicals. Sacco and Vanzetti, Italian immigrants and anarchists, were charged with robbery and murder in 1920 amidst anti-foreign and anti-radical sentiment. Despite limited evidence linking them to the crime, their executions in 1927 sparked protests and raised questions about the justice system's treatment of defendants based on their political beliefs.
