Yep, that's unfortunately true. That's why inner city news don't report new buildings or new laws as often as they do homicides, robberies and other crimes. That is the stuff that gets viewers, and gets advertising money.
I've read that a fun thing to do is watch the news during sweeps week. Things are always oversold. There are supposedly more of the "10 things in your home want you dead...stay tuned at 11" reports. I've also heard that a prime example was some Kansas station that reported "Hundreds dead in highway accident." They were talking about a truck full of pigs that flipped...yeah.
