I overheard a segment from someone my brother was listening to that broke down by decade how many shootings like this occurred. 1950's had 0 or 1, 60's were also very tame, maybe it was 1 or 2. 70s a little more, etc but when the 90's and 2000's hit they went up sharply.

The point was that guns weren't doing this, something else was, like mental illness or meds.

I knew this before, but never so concisely laid out like that.
