Final answer:
During the Red Scare following WWI, the Palmer Raids led to the arrest of thousands and the deportation of hundreds without proof, targeting homes and radical groups.
Step-by-step explanation:
The Palmer Raids rounded up hundreds of individuals, invaded private homes and properties, arrested thousands without proof, and deported hundreds. These raids were led by Attorney General A. Mitchell Palmer with assistance from J. Edgar Hoover. The raids targeted radical groups and alleged American radicals, leading to the arrests and deportation of a significant number of people. This historical event unfolded during a period of intense fear of communism and anarchism in the United States known as the Red Scare. This was a time of a growing nativism sentiment and the formation of the American Civil Liberties Union in response to the government's actions.
