From CNN:

Not all deaths involving guns are the same — therefore trying to address each incident from the same point of view is futile. Until we learn more about Alexis — the events leading up to the shootings and the motive — the tragedy in Washington should not be used as catalyst for a conversation about gun control.

Because like it or not, the folks spraying our cities with bullets are not NRA members or legal gun owners. And despite the tendency to tie it all together, they have nothing to do with the Adam Lanzas of the world.
