“The commission concludes that, oh yes, let’s expand the FCC’s power to regulate broadcaster content with a new law, but cautions Congress on the difficulty of actually defining excessive violence. One person’s example of gratuitous media violence is another person’s idea of a film classic, a fantastic war documentary, or a brilliant newscast from an urban riot. But far from being daunted by the perpetual needlework of OK’ing one kind of violence because it’s artistic, historical, or newsworthy but nixing another as too wanton, the FCC appears to relish the idea of refereeing all television programming everywhere.”
