What are the two reasons why mitchell palmer raided immigrants home?

Mitchell Palmer raided immigrants' homes primarily due to the fear of radicalism and the rise of communism during the post-World War I period, known as the Red Scare. The raids aimed to target and deport suspected anarchists and communists, fueled by a broader concern over domestic terrorism following events like the 1919 bombings. Additionally, these actions were politically motivated, as Palmer sought to bolster his own position and appeal to public fears regarding Immigration and national security.
