They're the donut people.

You want to hear Moore’s attempt at urban jeremiad? “This awful city, it screams like an abattoir full of retarded children.” That line from the book may be meant as a punky retread of James Ellroy, but it sounds to me like a writer trying much, much too hard; either way, it makes it directly into the movie, as one of Rorschach’s voice-overs.

Lane implies here that the line isn’t originally Rorschach’s — that is, that it’s Moore’s own bad writing, and not the bad writing of one of Moore’s characters.
