Cliff,
It's a good Message. The more precautions that are taken the less likely someone will get hurt while doing Electrical work.
I get mixed feelings about how much it might really help the Homeowner if it gives them the confidence to do something they really shouldn't be doing. That's another story, but if this is geared to the Homeowner/DIYer perhaps a reminder about what can still happen with a bad or unsafe installation should be added.
Happy New Year,
Bill
