Nobody is going to be raped in the parking ramp at your office EVERY DAY. It may happen once but statistically it'll never happen again in that location.
Someone may be murdered on the street you ride your bike to work each morning. And, unless you live in Compton its unlikely to ever happen again. And if you do live in Compton why the hell are you riding your bike to work through a war zone you moron?! :)
But lets just say these things do in fact happen. Likely, you're not going to hear about them from the news. You're going to hear about them from a friend, family member, and/or co-worker long before seeing it on the news.
The point of this article isn't that the news is bad because its news. Its that news is bad because all the media outlets focus on the wrong things (rapes, murders, etc...). Things you actually don't need the news for in order to stay informed.
Where the news can be great is keeping a populace informed of their government. Nixon was taken down by news done well. Unfortunately, in the day of Fox News, being an informed populace is even becoming difficult.
