"The U.S. Secret Service has a particular stake in preventing incidents of targeted violence toward government officials, facilities, and sites. In December 2015, the agency's National Threat Assessment Center published Attacks on Federal Government 2001-2013: Threat Assessment Considerations, a report that studied 43 attacks targeting federal government facilities and officials that occurred between 2001 and 2013. More than half of the attacks occurred outside of the Washington, D.C., metro area, affecting communities in 15 states. In these incidents, almost two-thirds of the attackers selected targets within 25 miles of their homes. Further, the offenders targeted not only federal buildings, but also federal officials at their private residences, federally funded university research labs, and federal agencies with offices in commercial buildings and shopping centers."
