NBC

I don't really have big objection to NBC's airing of the tape save for the insensitivity to the families so soon after the event. Having said that, Why not say:

We received this package from the killer, but we here at NBC have chosen not to air [even if only temporarily] the video. We may air it at a future time once things have settled down. For now, though, out of respect for the families and the Hokie family, we withhold.

This would have been the way to go...sing our own praises while doing the right thing.
