I'm plagiarizing this, but:
Shut off the TV news. In fact, shut off any news source that comes out more than once a week. Scratch that: once a month. There is nothing in the national or international news that is of the faintest relevance to you on a daily basis. It's far away; it does not affect you and you can't affect it. I know you're outraged by Boko Haram and the Gaza and whatever else, but it didn't actually affect you.
And you know how much your outraged posts on Facebook accomplished? F***-all. And that satisfied feeling that you achieved something today by being outraged on Facebook is fake; it prevented you from doing something that actually mattered.
If you must get the news today, get the local news. Find out what's happening in your community. What your neighbors are doing matters, and you can affect it.
The national news is effectively fictional. It's some kind of cosmic good-versus-evil argument in which 99% of of everything is posturing. If you got that a week later, or a month later, it would do an equal amount of good, and you'd have better perspective on it. There is no miracle cure or wonder food or subatomic particle so damned important that it can't wait four weeks for you to hear about it.
Actually, I was initially going to write about crime rates, which answers the question more directly. If you're worried about crime, it's because you're getting your news from a news source designed to keep you coming back every day. Here:

That's it. You're done. Nothing you see on the news tonight, this month, or anywhere between here and the next national census is going to radically alter the direction of this graph. You don't need to watch the news tonight to find out the details. You're safer than you've been any time in my lifetime, and probably yours, and everybody trying to tell you differently should become a victim of violent crime.
And that generalizes to everything else you hear on the news except perhaps the weather. Even the sports news is far less relevant than you're pretending it is. You didn't play it, and that team doesn't give a flying fig whether you're cheering for them or not.
Stop treating all of this as if finding out about it somehow makes you a good citizen. It doesn't. It's entertainment, at best. At least with the sports you can admit to yourself that it's entertainment, not news, though honestly you'd be better off if you went the hell outside and played the game (or any game) yourself.
So to sum up: shut off the news. Go outside. Meet actual people in your actual vicinity. Stop pretending there's virtue in your nightly outrage fest, because statistically speaking, there isn't any. On those immensely rare occasions when something big does affect you, like a war or a volcano or something, I swear you'll find out somehow.
