Audio problem: When Bobby's brother dials 911 you hear 3 tones (for the 3 digits he dials). But the 3 tones aren't the right tones you hear when you dial 911 from a touch tone phone. In fact the 2nd and 3rd tones should be the same because it's the same digit but they were different. As if someone just dialed 3 random digits. And there's no doubt he dialed 911 because the operator answers "911". (00:56:55)
