The US is safer than ever — and Americans don’t have any idea

There is half as much crime in the US right now as there was about 25 years ago. Both violent and property crime have declined pretty steadily since the early 1990s. But at any given time, if you ask Americans about it, between half and three-quarters of them will say that crime rates are going up.
