Mass shootings and other forms of mass murder sort of started with the University of Texas tower shooter back in 1966. They’ve been a constant ever since. Basically most of my life. A few of them have been stopped by good citizens with guns. Bless those brave individuals. Guns aren’t the only means of course as 9/11 clearly showed. Any evil idiot can kill many with a vehicle as has also happened. To me it represents people without God and life for many becomes meaningless. I think we can say the 1960s was a watershed which changed that life outlook for many in the US and also around the world.
The Unruh guy in Camden NJ was before that.
