The only problem with that is that violent crime has actually been falling in the United States for quite some time.
From the FBI Statistics page:
"There were an estimated 366.7 violent crimes per 100,000 inhabitants in 2019, a rate that dropped 1.0 percent when compared with the 2018 estimated violent crime rate and fell 9.3 percent from the 2010 estimate."

But you are not alone in thinking it's getting worse. The media's infatuation with violent crime over-emphasises it and what I've come to call 'The Gunfighter Industrial Complex" exploits it.
Forty years ago when I started shooting you never even saw a human silhouette target on the range. It was mostly a bunch of guys interested in precision (if not formal bullseye) and the pistol range was 25 yards. Nowadays everybody is practicing killing people.
If you go look at the statistics, any ones you want massaged any way you want, you can only come to the conclusion that there's a 99%+ chance they'll never need the gun they're carrying. I'd venture a guess that negligent discharges are more likely. But they don't keep stats on that anywhere I can find.
Of course, that's in the aggregate and one's risk profile may be greater. But most of the people I know that always carry are probably well below the average risk.
Don't take this to mean that I'm opposed to concealed carry.
