A. Mitchell Palmer took action by starting a division within the Justice Department after declaring that "a blaze of revolution" was "burning up the foundations of society."

The division is commonly known as the Federal Bureau of Investigation, or the FBI and J. Edgar Hoover was the head of the division.

After the attacks, there was no evidence that pointed to any particular group of people, but Palmer's agents targeted the foreign-born.
