The United States relies on a wide range of protection measures for witnesses and victims. Protection is provided not only to persons that actually testify in criminal proceedings, but also to potential witnesses, as well as the immediate and extended family members of the witnesses and potential witnesses and the persons closely associated with them, if an analysis of the threat determines that such protection is necessary. From an operational point of view, the protection of witnesses’ and victims’ physical security can be secured through the Federal Witness Security Program, if these persons meet the requirements for participation in that Program. Other procedures are also in place to provide limited protection through financial assistance for relocation.
