Around 6:30 this evening I was preparing the "apéritive" in the kitchen, kids watching some TV when all of a sudden my eldest daughter comes in asking about a man who was very sick and bloody with a lot of people around him screaming. Then you curse yourself (for not having surveyed) and the TV-channels (for broadcasting that on such an hour) and try to explain to a 7-year old what the war in Libya was about.
Set aside the time of broadcasting; for us adults I think it is admissible to publish the footage. It is a final stage in a war in which we have participated, either directly or by sitting before the TV-set and reading the newspapers. In the end that civil war converged into the hunt for Khaddafi / Ghatafi and Hussein whilst camera-teams and mobile telephones recorded everything newsworthy, including "the finale" with a wounded man dragged from a truck or a condemned man hanged to death.
As for incidents like the one with that little girl: there is no excuse for non-assistance, even for a cameraman. I know of cases where camera-crews and other filming by-standers have been prosecuted and convicted for that reason. As for the (commercial) TV-channels; they broadcast what their spectators (in general)want to see. The only way to change that is to "vote with your channel-dial"; don't watch it anymore.
@ Peter: you know how it is with pornography of any kind: nobody watches it, but strangely enough there's a multi-billion market with according commercial interests ;-)
