The trial of Sacco and Vanzetti was a case in which two men born in Italy were convicted of murdering a guard and a paymaster during an armed robbery. They were both anarchists. Anti-immigrant and anti-leftist beliefs were probably a factor in their conviction. All the appeals to higher courts were rejected, and the case drew worldwide attention.
The Scopes trial wouldn't be right because it was about a teacher teaching about evolution, which was against the law. The Teapot Dome Scandal was a bribery scandal, and the stock market crash was an economic event.
