Miller argues that the tactics of misdirection and guilt by association used in the McCarthy era are similar to those used during the Salem witch trials..
Step-by-step explanation:
In Arthur Miller's play, he argues that the tactics of misdirection and guilt by association used in the McCarthy era are similar to those used during the Salem witch trials.
The characters in the play who sought evidence before convicting those accused of crimes soon found themselves among the defendants, just as those accused of witchcraft had no way to prove their innocence. Miller used these events to make his audience consider the dangers of McCarthyism and the importance of fairness and justice in society.
