"More than two hundred and sixty five people have been killed in multiple death armed attacks since the Littleton, Colorado Columbine High School shootings in 1999 through the most recent armed attack at the Sandy Hook Elementary School in Newtown, Connecticut. As members of the fire service we now know that no-notice events such as Aurora, Colorado; Portland, Oregon and Sandy Hook have and will occur anywhere, at any place, to anyone or demographic. There is not one among us who hasn't been touched by the more recent events in Webster, New York where firefighters became the target of a planned armed attack. Accordingly, the U.S. Fire Administration (USFA) is undertaking a study of these events in both this country and internationally to identify risk commonalities and best practices to successfully respond to these diverse incidents. The topical report will be released later this month and is currently undergoing extensive peer reviews. Extraordinary efforts on the part of local fire/rescue and EMS [Emergency Medical Services] agencies have to be taken in order to protect fire and EMS personnel and experience maximum success in saving civilian lives. These events may play out over an extended period of time, requiring large EMS triage, treatment and transportation efforts, under dangerous and unfamiliar conditions to fire and EMS personnel."
