Like your country is slowly collapsing and eating itself from the inside.
These types of events are so normalized in American society and due to your 2nd amendment and no politician seriously willing to make changes or draft legislation (due to fear of those millions of armed gun nuts), it’s a recipe for disaster. Hell you could go deeper into some of the social, political and economic issues plaguing America that is also part of why we see this type of mayhem - Violence is apart of American society.
From its very inception, the country was founded on the barbaric treatment of Native Americans and African slaves and when the violence is glorified in every form of entertainment (music, television, film, video games) and in the face of your average American everyday of their life since they are born with a population of 300 million +, it’s a ticking time bomb.
