The attorney general has been requested by me to instruct the Federal Bureau of Investigation of the Department of Justice to take charge of investigative work in matters relating to espionage, sabotage, and violations of neutrality regulations.
This task must be conducted in a comprehensive and effective manner on a national basis, and all information must be carefully sifted out and correlated in order to avoid confusion and irresponsibility.
To this end I request all police officers, sheriffs, and all other law enforcement officers in the United States promptly to turn over to the nearest representative of the Federal Bureau of Investigation any information obtained by them relating to espionage, counterespionage, sabotage, subversive activities and violations of the neutrality law.
Police Cooperation
On September 6, 1939, I issued a directive providing that the Federal Bureau of Investigation of the Department of Justice should take charge of investigative work in matters relating to espionage, sabotage, and violations of the neutrality regulations, pointing out that the investigations must be conducted in a comprehensive manner, on a national basis, and all information carefully sifted out and correlated in order to avoid confusion and irresponsibility.
I then requested all police officers, sheriffs, and other law enforcement officers in the United States, promptly to turn over to the nearest representatives of the Federal Bureau of Investigation any such information.
I am again calling the attention of all enforcement officers to the request that they report all such information promptly to the nearest field representative of the Federal Bureau of Investigation, which is charged with the responsibility of correlating this material and referring matters which are under the jurisdiction of any other Federal agency with responsibilities in this field to the appropriate agency.
I suggest that all patriotic organizations and individuals likewise report all such information relating to espionage and related matters to the Federal Bureau of Investigation in the same manner.
I am confident that all law enforcement officers, who are now rendering such invaluable assistance toward the success of the internal safety of our country, will cooperate in this matter.
