For a seditious conspiracy charge to be effected, a crime need only be planned, it need not be actually attempted. According to Andres Torres and Jose E. Velazquez, the accusation of seditious conspiracy is of political nature and was used almost exclusively against Puerto Rican independentistas in the twentieth century. However, the act was also used in the twentieth century against communists and radicals (United Freedom Front, the Provisional IRA in Massachusetts), neo-Nazis, and Islamic terrorists including Omar Abdel-Rahman. This is respective of the state sedition laws, used to persecute hundreds of communists, socialists and labor leaders.
