I was thinking the same thing, since I was both alive in the 90s, and have read several books that talk talk about all the various theories on why crime declined so much in the 90s. Then I went to look and it seems since 2016 we’ve been on a meteoric rise and have surpassed the 90s numbers, at least when it comes to gun violence. It’s going up faster than it dropped.
