It doesn't take many people with nothing to live for to become problematic for existing power structures.
For a couple of years now, I've had this mental image of an angry young man, maybe an incel; driving somewhere to kill himself, and coming across an RBT (Random breath test/DUI stop).
Rightly or wrongly he blames the system for his woes; and with nothing to lose he just accelerates and runs them all over. Like any suicide, it doesn't have to be a 'good' idea for long.
It would normally be an isolated incident, but with enough anti-authority sentiment in the community; we see a few instathots praising his actions while shaking their cleavage at the camera. Suddenly there's a new National pass-time.
We had a shooting in Qld late last year, a throuple, their neighbour and two cops all died. If that had happened 20 years ago, the community outrage and displays of support for the police would've been overwhelming.
Nobody I've spoken to appears to care. Like at all. A newsreader mentioned candlelight vigils, but I never saw footage.
Next time the politicians demand the police enforce lockdowns, I really hope they're told to pound sand. For everyone's sake.
I don't know if you remember, but back "in the day" I wrote a series of horror stories called "Random acts of Violence" - it has been an idea I have had since a kid essentially. But of course, nothing is random, right?
All of these things have a long line of catalysts to push people to the point that they break and coupled with the variance in personalities and abilities for self control etc, it is bound to happen. It is an economic reaction, where incentives align to drive a trend and set of a actions and reactions.
Nothing to live for or trapped in the corner, when it is happening to tens of millions of people globally at the same time, there is going to be a percentage who will take the next step, which will make that step smaller for those just behind to follow.
