In some situations, we disable commenting on stories. We do so by following certain criteria, such as if the comments may cause harm, or if there is a risk that they may break the law.

For example, we don't enable comments on stories about kidnapping, as we wouldn't want to inadvertently publish something that would assist the abductors.

We disable comments on stories concerning court cases that involve a publication ban, and on stories related to sexual assault, in order to protect the identity of the victim.

And often we don't allow comments on stories related to the death of individuals as we don't want to publish anything that may be hurtful for the family.

The decision to disable comments on a story is made after discussion among the news editorial team at CBC.ca.

What you are hearing is a Described Video soundtrack on CBC Television. DV allows vision-impaired Canadians greater access to CBC Television programming by describing the scene and action during pauses in dialogue. The DV soundtrack is delivered on Secondary Audio Program or SAP which is an audio setting on your Television. To turn off the narration, you need to have your television audio set with the SAP feature off and stereo sound on.

Turning SAP on and off is done on most television sets through a menu using the remote control. Every television set is different, so the best way to do that is to follow the instructions in your owner's manual.
