Explanation:

In 1921, Nicola Sacco and Bartolomeo Vanzetti, both Italian-Americans, were sentenced for theft and murder. In spite of the fact that the contentions brought against them were for the most part disproven in court, the way that the two men were known radicals biased the judge and jury against them. On April 9, 1927, Sacco and Vanzetti's last intrigue was rejected, and the two were condemned to death. Felix Frankfurter, at that point an educator at Harvard Law School, was viewed as the most conspicuous and decent commentator of the preliminary. He was appointed to the Supreme Court by Franklin Delano Roosevelt in 1939
