90% are mature? Have you watched any group of teens these days? Having been a teenager once, I can recall those days. We were anything but mature.

I have to disagree with HyperDave as well. I don't think that Nick Berg's head being cut off is something I'd define as "history". It's a brutal act of violence against a human being. A singular act in a sea of brutality. But, it's not a historical event worthy of turning into a teaching lesson.

I also think it's extremely insensitive to the Berg family. Their son was taken from them in a very cruel act.

About the only thing that showing a video like this to kids/teens/adults is going to do is add more fuel to the fire. People are going to see "how cruel those Muslims were to that guy" and they're going to start forming opinions of hatred against all Muslims. The worst groups of all to show a video like this to are those who still have an impressionable mind. Teens and younger children will be heavily influenced by the violence shown in something like this.

Remember events like Columbine? They have councelors all over the school helping kids deal with the trama of the violent act that happened. Even those who didn't actually witness the shootings were tramatized. Don't you think a video of someone's head being cut off ranks up there a bit on the trama scale?

The whole incident should be left alone at this point. Let the family have their memories. Schools don't need to be showing this type of stuff to kids. There's no educational value in it as far as I can see.
