The problem, as I see it, is that the problems are exaggerated by local news organizations seeking out the more sensational attention-grabbing stories and presenting them as representative of the norm.
This, coupled with the vast increase in news hours being broadcast, and the need to fill those hours with something spectacular, and the prevalence of mobile phones that can take video, is a large part of the problem.
I see a lot more news about violent crime today than I did twenty years ago, because more crimes are being videoed, more violence is being broadcast, and the local news channels are becoming less and less averse to using footage from the other side of the world, rather than the other side of the city.
Twenty years ago, a report about a cop being beaten up would only have been news if it had happened in my own town. Because TV stations knew people didn't care to watch news stories about stuff in other states, or other countries. But that was when the report was just some anchorman reading a teleprompter. Nowadays, if there's footage of a fist impacting a cop's nose, it's gonna make the news, even if the cop in question is half a world away.
And Channel 9 won't mention the city it happened in in any of their trailers. "See the shocking moment when a routine traffic stop turns violent, putting an officer in hospital - Watch Channel 9 news at six!", will be likely the majority of the coverage many people see of this incident. Only the tiny subset who bother to watch the main bulletin at six will discover that the incident was in Bumfuck, Alabama, and not in Crestmead.
A Crestmead resident could easily feel that the world is becoming lawless and dangerous. But it's not; It's just becoming easier to get ratings by implying that it is.
