In America, there was a fear of Communism when labor unions embrace communism and bombs are mailed to government officials. Palmer and Hoover start the Palmer raids. They hunted suspected communists, socialists, and anarchist. They will invade homes and offices, jail people without lawyers, and hundreds of foreign born radicals will be deported. The policemen in the cartoon represent the acts in the US that deported foreigners. There is a bomb in the background which shows that Americans were being bombed.
