Perhaps our virulent violence is at base the product of a long festering cancer; a thing inherent in a country that’s not truly eradicated what comes from its’ founding as a society enshrining slavery in the very fabric of its constitution. The sickness isn’t well suppressed now.
There’s a reservoir of violence & suppressed hatred on both sides of the equation that still smolders. It’s not going to go out without attention. It’s periodically like the incompletely extinguished campfire that flares into a general conflagration that then burns down a forest.
