The families of the deceased. My heart goes out to all of these people. I was affected by Phil Hartman's murder in a different way. When a personal tragedy happens close to us, we respond in personal terms, maybe an empathic emotional connection to the survivors and the victims, perhaps scorn for the perpetrators of the crime, and certainly outrage at the very existence of the event. But when we lose a celebrity, well, a stranger response ensues.
Death is a sad thing, period.
Especially an untimely death borne of violence. It's not terribly hard to make a connection to such a thing. Except, well, it's different. Phil is the guy you loved to watch and never knew it. I remember very distinctly growing up with that cast which included Meyers, Carvey, Jan Hooks, Victoria Jackson, Jon Lovitz, Dennis Miller, and Kevin Nealon, and eventually also featured the likes of Sandler, Farley, David Spade, and Chris Rock.
