I hate to nitpick but from my perspective I do not put the number of victims of terrorism on US soil since 9/11 at zero. The DC sniper case fallen and the single gunman who killed I think 2 at the LAX El Al counter I consider victims of terrorism. There may be some other case or cases that are slipping my mind too. The number is low of course in comparison to what happened on 9/11. Some here on FR also think the plane that crashsed right after takeoff from one of the NY airports some time after 9/11 might be terrorsism but explained away as some catastrophic mechanical thing.
correction....I don't think the LAX El Al counter gunman as a victim but the 2 he slayed.
