While Clinton's inappropriate personal life deserved some remedial and punitive action, and maybe could not have escaped repraisal, the political inquisition into the President's personal life was a major fiasco that indicted them all for incompetence - especially when public opinion was always against all of it. So unfortunately while posturing on violence, they may just bungle into passing some kind of legislation against media violence modeled on pornography laws, that will actually stand. The ramifications are ugly. Pornography is something that we tolerate in adults and prevent children from exposure to until it is their mature choice. But violence in the media is something we accept in adult media and minimize from children's view, knowing that they will be exposed to violent stories or real violence in the streets as a world condition as they mature.
Violence is a primitive instinct.
I don't think anyone had to sail thousands of miles across the ocean to teach them violence, or show them a violent movie. Given enough pressure, people will become violent. If we are not teaching people how to resolve disputes in nonviolent ways, then the blame is on us. Eventually the people of Easter Island worked out ways of surviving together. I suspect that we are somewhat more capable of doing the same.
