Statistically speaking, it's delusional for people to live in fear of crime when crime is as low as it's ever been. The chances of a stranger attacking you are incredibly low. Not only is overall crime down but most violent crime that does occur is between people who know each other, not some random stranger. Getting attacked or shot or trafficked by a stranger is so rare compared to dying in a car crash or of an illness.

Yet many people still worry about strangers attacking them and freak out about mythical riot and unpoliced zones in "urban" areas, when in reality all of this stuff is way overblown. People spend years living in unnecessary fear and they'd be better off health-wise not stressing about it. 

Arguably, we are living in the most peaceful and cooperative time in all US history, and possibly all the world. But people who realize they're safe don't purchase lots of firearms to protect themselves. People who realize they're safe don't have a desire to put a lot of "scary" minorities into private prisons. People who realize they're safe don't want to build idiotic walls on the border. 

But people who are told to be afraid want all these things, and there's one party to serve those people, to cater to their ridiculously inflated fears.
