What were the Palmer Raids?

Example:

The Palmer Raids were important because they showed the fear and suspicion in the U.S. after World War I, particularly towards immigrants and those with radical political beliefs. These raids highlighted tensions around national security, civil liberties, and the balance between safety and freedom, issues that remain relevant today. The fear of communism, known as the "Red Scare," led to the arrest and deportation of many people without proper evidence or trials. Today, similar debates happen concerning how to protect people while respecting their rights, such as discussions about surveillance and privacy. These ideas affect average people through laws and policies that can impact how much privacy they have in their own lives, like how their personal information is handled online.
