Unrecognized and uncontrolled mental sickness. More people, more psychoactive drugs, more innate mental sickness, more reporting, more violent images pumped into society, more hard ,sharp , explosive objects, and less of a desire to suppress a mentally sick persons “freedoms”. Especially if the person is some kind of “struggling, down and outer”
At least that is one explanation for the spate of random and/or familial murders. IMHO
