Okay, after reading all the comments , I listened to the calls and I really don't get where all this suspicion comes from. Or the weird vibes. In the first call, he was initially rattled when they transferred him to the 911 line. I would have been too. It's drummed into all our heads not to call 911 unless it's a life-threatening emergency. So, he calls a non-emergency number and zip, they transfer him right to 911.
And the oh-so-scandalous "singing" he did was when he was looking for something to help him tell the 911 operator what area is he was talking about. He's just making noise so she would know he's still there. People do it all the time.
In the second call, he had more street names, since he'd already been asked those questions. And, if you notice, at 1:45 or so, the operator asked him the name of the school, and he said he didn't really pay attention because he just looks at the meter numbers on his reader. Just as someone else explained earlier in this thread.
And, as for the inappropriate "laughter" when he said he couldn't remain anonymous if they find a body. It sounded like nervous laughter to me. Really not unusual. I personally crack jokes like a stand up comic when I'm very nervous. No telling what stupid thing I might have said under the same circumstances.
But after reading some of these posts, I can certainly understand why people are more and more reluctant to "get involved" these days. We can't decry the fact that people are reluctant to stand up and do the right thing if we immediately start treating everyone who does the right thing like a suspect. JMO.
