I think that's an unfair characterization. A decade ago, the broadcasters themselves acknowledged that there was a problem with regard to TV violence. That's why they developed the code in the first place, and that's why they have supported it. In a society in which we're all affected by television violence, the broadcasters have stated that the conditions in the code are fair and appropriate. So if there's censorship going on, it's willing, voluntary.
We have forms of censorship in society for obvious reasons. Journalists, for example, do not typically report on teen suicide because they know the likelihood of imitation is high. That's a form of self-censorship that has the interests of the larger society at heart. I think the violence code fits in that tradition.
