> They collected a fine from you and you have no money to buy yourself life saving medicine and you die. They killed you by taking away you last money at the moment your life depended on it.
I am probably more aware of this than most. In addition to the clinical example, it actually occurs (in the US) in family law a fair amount more than I see admitted in the public discourse.
> Probability of killing you obviously increases as escalation progresses but never reaches 100%
Well, yes. But uncertainty abounds on both sides. Neither of the counter-parties to the violent transaction know each other well enough to prevent a certain non-linear ratchety-ness to the escalation.
I am not for cop's killing civians ... but I don't see any other outcome to the environment (cultural context, and situational uncertainty) that we have (collectively) created.
I will admit that we might be wise to hire calmer officers of the law, but, on average, when they have come to "get me", I've found them pretty calm. (Some nicer and more accomodating than others - but usually mostly professional).
EDIT: Comments in this thread may make me appear as if I am some sort of bad-man or out-law. I tend to not think of myself that way - I don't rob, break-in, assault, rape, kidnap or murder. Or even take stuff that isn't mine. Or break or paint on other people's property. The US regulatory system is complex and one might get caught up in any number of ways. The other thing, though, is that I am curious, and often wonder: What would they do if a non-violent offender just says "no"? The direct consequenses are usually not very harsh, but there are some knock-on effects that do impair one's life. "Civil disobediance" (whatever that means) can be costly over time. (Maybe that's the point of it? IDK)
