Images.
There is no media conspiracy to silence 9/11 images.
In Europe unedited images of body parts were shown in newspapers and on television. In America these images were edited because the media (rightly) knows there is an organised censorship element in the country against disturbing images - for the sake of the children of course. You know the censorship for the family's sake's types - they object even to showing 'Saving Private Ryan' and 'Schindler's List' unedited.
