The bizarro scene is even more amazing considering the interview that follows. At the interview's 4:00 minute mark, we see Herzog sitting with Treadwell's ex-girlfriend, listening to the tape that Treadwell made during the attack; the lens cap was on Treadwell's video camera, so only the sound was captured. Herzog whispers to the woman: "Julie, you must never listen to this." "I know, Werner," she replies tearfully, "I'm never going to." (Herzog chose not to include the audio in his film.) In another clip, Herzog describes Treadwell's irrational fearlessness of nature, and his belief that the natural world was in "balance and harmony". "I believe the common denominator of the universe is not harmony," intones Herzog, "but chaos, hostility, and murder."
Maybe the shooter was just trying to drive the point home.
