The connection between the Aurora shooting and the single page vignette from "The Dark Knight Returns" graphic novel is tenuous, at best.
In that scene, a pathetic, mentally impaired individual, hearing messages in music played backwards, walks into a porno theater, and prepares to open fire. The next panel is an immediate cut to a television reporter, announcing that a "Batman inspired shooting" has taken place in a porno theater.
The obvious point here being, that even though this person was not motivated by anything other than the voices in his head (and a TV preacher who claimed that rock music contained backmasking), the Media immediately makes the connection to his violence and Batman (who, in this story, has returned after an absence of 10 years.)
The irony of this one page of a comic book being linked to the events at Aurora may be lost on the "reporters" of HLN, but not on me.
