The haphazard fashion in which the Salem witch trials were conducted contributed to changes in U.S. court procedures, including rights to legal representation and cross-examination of accusers as well as the presumption that one is innocent until proven guilty. The Salem trials also went on to become a powerful metaphor for the anticommunist hearings led by U.S. Sen. Joseph McCarthy during the Red Scare of the 1950s, famously in the form of Arthur Miller’s allegorical play The Crucible (1953).
