This was someone who was not involved in anything risky; he was walking down a sidewalk to his apartment. It doesn't get much more mundane than that.

It's not a matter of punishment or revenge, but closure. We'd like to put an end to this, and learn why it happened.

We?re hoping that somebody out there has a good heart and will come forward. It?s not a question of punishment or revenge for us. It?s really a question of closure.

Let me assure you, there isn't anybody walking up and down my sidewalk these days,

I'd rather they walk on a sidewalk, ... The road's not that wide.

If you had a friend who was a tightrope walker, and you were walking down a sidewalk, and he fell, that would be completely unacceptable...
