I think you're right on with your issue....
Fine to broadcast that, just give fair warming, so the listener can decide if they (or who ever is riding with them) wants to hear what is about to shared. I think it may be harder to do during a normal type of news cast, but if it's a news program with different segments, then they should.
I listen to NPR here (National Public Radio), and if they do a segment on something that may not be suitable for younger listeners, they give a warning.
Protecting my childern from the world is doing them an injustice, but wherever possible, I'd like to have some say in the initial level and degree to which they are exposed to the things of this world. I appreciate when things like that come up, because as a parent it may open a door for a conversation I would have a hard time opening myself.
All that coming from a guy who has a 3 1/2 and 18 month old with another due in June. I haven't had to have a lot of those conversations, but enough (death of a family member, neighbor, pet, etc.), that I have an idea about how I'd like some other BIG conversations that are coming to go (dating, sex, drugs, freinds influence, etc.)
Some really good response here, too!
