If it puts your mind at ease at all, crime (violent and otherwise) had been on a decline from 1993 until 2016 and while it has risen since 2016, it still hasn't hit pre-'93 levels last I saw. Furthermore despite what you'd expect, those AR-15s are responsible for less than 500 (all rifles) of our 60,000 gun deaths, which is 0.833333333333% of our gun deaths. In fact, mass shootings account for less than 0.2% of our gun deaths per year. So, I mean "any is too much" yes, but it isn't near as bad as it seems. source
