By every objective measure the world is getting safer and better overall. The media focuses on the negative, amplifies it (especially in our post-truth, clicks = money age) and is themselves manipulated by jackasses like Trump to make everything seem horrible. The NRA, the Republicans, the media (even the liberal media) make us all feel unsafe. It makes money. And in the US right now, our gun problem is way out of control, but the tide is turning and will start to really turn rapidly now that the kids are fighting for their lives and coming of voting age.
In general, WORLDWIDE, things are getting far better. Civilized nations continue to get happier and richer (I'm calling an exception here for geocentric screwed up USA - but the trend still stands)
This can be verified almost anywhere at this point. Poverty will decline by 2020 from 30% to 15% as education improves, quality of life improves, cost of goods decreases, crypto includes the most politically and economically disadvantaged in the world economy, and a lot more.
