This is a documentary, which means its real life. This was an ugly horrible and devastating event...there is absolutely no reason why it should be edited in any fashion. If you think your children aren't mature enough to handle it, send them to bed or watch something else. If your kids are mature enough to handle it but you still wont let them watch it then shame on you. I know for a fact that learning to how to react and deal with real life situations that arent pretty and polite is a necessary skill. If you send your kids off to school and heaven forbid theres some kind of terrorist attack at said school, do you want them standing up pointing to the kid next them in disbelief because they said a "naughty word?"
Are you addressing your comments to me, or to the AFA? I think the documentary should be shown as the directors intended - rough language and all.
