US Presidency
1889

In recommending such legislation I do not at all impeach either the general adequacy of the provision made by the State laws for the protection of all citizens or the general good disposition of those charged with the execution of such laws to give protection to the officers of the United States. The duty of protecting its officers, as such, and of punishing those who assault them on account of their official acts should not be devolved expressly or by acquiescence upon the local authorities. Events which have been brought to my attention happening in other parts of the country have also suggested the propriety of extending by legislation fuller protection to those who may be called as witnesses in the courts of the United States. The law compels those who are supposed to have knowledge of public offenses to attend upon our courts and grand juries and to give evidence. There is a manifest resulting duty that these witnesses shall be protected from injury on account of their testimony.
