Or the anthrax attacks. Or the crash of Flight 587. Or Newtown. Or Aurora. Or any number of other kind of terror attacks (Madrid, London (yeah, I know, not US but still), suicide bombings against US forces in Iraq/Afghanistan, Fort Hood, etc.)

Exactly. Since when is the death/murder/assassination of someone that works in a location with an assumed risk of injury or death more “tragic” then the murder of 20 1st graders.
