Yes, but only because the media puts it there.
You can't complain about films, video games and television shows containing too much sex and violence when anyone can turn on the news and see the same. The media enjoys hyping things up and they have more power than I think they realise. If they were to begin using the news to celebrate the goodness in the world, perhaps the world would become a better place.
I'm not saying that stories about war or violence are not to be shown on the news, of course they are, but they do dominate.
