It's Hard to Understand?

I continually tell people that I remember very few mass shootings when I was a kid. The only one I remembered was the Texas Tower massacre. Few people believe me when I say it but now I just looked up the stats. Here they are. It is mind boggling to see the acceleration of these kinds of incidents. It is even more mind boggling trying to figure out why??
