Anti-redism and antiforeignism were reflected in a notorious case, and were convicted in 1921 of the murder of a Massachusetts paymaster and his guard.

Nicola Sacco and Bartolomeo Vanzotti

Explanation:

In 1921, Nicola Sacco and Bartolomeo Vanzetti, both Italian-Americans, were convicted of robbery and murder. Although the arguments brought against them were mostly disproven in court, the fact that the two men were known radicals (and that their trial took place during the height of the Red Scare) prejudiced the judge and jury against them.
