Modern Day Witch Hunts
Arizona Law states that you can question someone's citizenship. This law mirrors the witch-hunts represented in the Crucible, because people are able to make assumptions based off of people's appearance and actions. Many people suspected of being immigrants are discriminated against and some cases the suspects can be deported.
Conclusion
The Red Scare and The Salem Witch hunt were both Rampant fear based on pure prejudice and lack of understanding. Trumped up charges, trials and effective punishment without any due process. And in both cases people were offered a chance to save themselves if they offered up other targets for the hunt. Arthur Miller's play gives huge insight to the corruption of both events in history.
