Listening to WND and they talked the radio not being shot because it doesn't make any sound like something metallic being shot. However, KC said that he faded out the sound of the alarm in the background as it was drawing away from the sounds in the room, so it could be that he hasn't added this sound for similar reasons.
I really want this to be true, cause shooting the blind girl makes me sad.
(Someone may have already posted around this idea, but I can't be bothered reading back to where I last was in this thread, sorry. I am prepared to take the non-thread read rap. )
