It doesn't mean the psychopath sniper's dumb as a rock. He may be using broken English as the only patois the authorities are able to understand since they seem to miss the point of the joke. To the sniper, they're the ones acting weird and retarded, not him. And this is his way of saying, combined with the latest shooting incident: "f*ck you and catch me if you dare."

Quite correct; actually, I think this person(s) is quite "clever."

Think maybe the note told Moose,"Dog,I want fiddy-fi million to stop busting caps."?
