“Sacco and Vanzetti were committed anarchists who had been active in many workers’ struggles. (…) Like most anarchists, the two were also active in their opposition to the First World War.
In April 1920, anarchist Andrea Salsedo was arrested and detained for 8 weeks. On the morning of May 3rd, he ‘fell’ to his death from the 14th floor window of a New York Dept. of Justice building. Sacco and Vanzetti, along with other comrades, immediately called a public meeting in Boston to protest. While out building support for this meeting they were arrested on suspicion of 'dangerous radical activities’.
The judge in the case, Judge Webster Thayer, said of Vanzetti: ’This man, although he may not have actually committed the crime attributed to him, is nevertheless morally culpable, because he is the enemy of our existing institutions.’ The foreman of the jury, a retired policeman, said in response to a friend of his who ventured the opinion that Sacco and Vanzetti might be innocent ’Damn them. They ought to hang anyway.’”
