Got this quote from the CBC editor-in-chief on the Chicago Tribune site linked on another thread:

"At the (Canadian Broadcasting Company), we debated the issue throughout the evening and made the decision that we would not broadcast any video or audio of this bizarre collection....We would report the essence of what the killer was saying, but not do what he so clearly hoped all media would do. To decide otherwise -- in our view -- would be to risk copycat killings.... As I watched them last night, sickened as I'm sure most viewers were, I imagined what kind of impact this broadcast would have on similarly deranged people. In horrific but real ways, this is their 15 seconds of fame. I had this awful and sad feeling that there were parents watching these excerpts on NBC who were unaware they they will lose their children in some future copycat killing triggered by these broadcasts."...
