It has everything to do with race. We are living in a Clockwork Orange world, where these kids have no reason to live, nothing to look forward to, little or no parental guidance, absent fathers, and are existential creations of our cruel welfare system, who can and do kill just for fun or for the hell of it. You can credit the Great Society for these aberrations of humanity. It will get worse. It reminds me of Camus book “The Stranger”, from 1942, where a man kills another man without any empathy or concern whatsoever because if life is meaningless, so are ethics, morality, right/wrong, etc. Life imitates art.
You’re being optimistic.
Within the black community, and to a growing extent within the Hispanic one, there are a couple generations that have been active taught race envy, suspicion, fearfulness and hatred.
