Steven Pinker describes how that went:
> "As a young teenager in proudly peaceable Canada during the romantic 1960s, I was a true believer in Bakunin's anarchism. I laughed off my parents' argument that if the government ever laid down its arms all hell would break loose. Our competing predictions were put to the test at 8:00 a.m. on October 7, 1969, when the Montreal police went on strike. By 11:20 am, the first bank was robbed. By noon, most of the downtown stores were closed because of looting. Within a few more hours, taxi drivers burned down the garage of a limousine service that competed with them for airport customers, a rooftop sniper killed a provincial police officer, rioters broke into several hotels and restaurants, and a doctor slew a burglar in his suburban home. By the end of the day, six banks had been robbed, a hundred shops had been looted, twelve fires had been set, forty carloads of storefront glass had been broken, and three million dollars in property damage had been inflicted, before city authorities had to call in the army and, of course, the Mounties to restore order. This decisive empirical test left my politics in tatters (and offered a foretaste of life as a scientist)."[16]
Apart from violence, there's another big thing that probably went missing, too - authorization for certain people to enter private property for reasons of the general good. The reason we call the police for welfare checks, for better or worse, is that nobody else has the right to enter your house. A doctor might be better suited to responding to someone undergoing a mental health crisis, but they can't break in. Similarly, you see stories of "police rescue deer from rooftop" or whatever because nobody else is authorized to climb onto random rooftops. If a society wants to get rid of the police, it needs to designate some other group to handle this use case. It can't simply get rid of the police.
A "natural experiment" of a world without police is quite unnatural: it's a world built up around the police with a sudden police-shaped gap in the middle.
To pick an analogy that should make sense to folks here, it's like shutting down your datacenter for 16 hours, suffering serious outages, and then concluding that your company absolutely needs its datacenter. Well, yes, it does today, but that's not what the people saying you should look at public cloud are advocating.
Isn't that reinventing the police, just with a different name?
I'm not at all saying that this by itself would eliminate racially-disproportionate violence done by the police (and you could argue that it'd risk increasing it, in fact - George Zimmerman was a neighborhood watch leader, not a cop). But it would straightforwardly eliminate a host of excesses from militarized equipment and training to asset forfeiture to the blue wall to qualified immunity to even (relatively) minor things like quotas.
(And to be clear, I'm not saying that "arm the populace and set up civilian watches" is a complete or good replacement for the police - I'm just saying it seems like the minimal possible step to take if you're carving the police out of a society that evolved around having police. If you don't even take that step, the results of a "natural experiment" of a day without police aren't meaningful. But it's not an actual policy proposal; a serious attempt at getting rid of the police would in fact want to be careful about making an even less-accountable shadow police.)
Imagine an armed and dangerous HOA, functioning as its own "community policy force."
What fresh hell is this?
This is the kind of behavior that I expect to see widely across America if we rely on random citizens to patrol instead of police. He was told by 911 to stay in his car, but instead he got out and shot Treyvon in supposed "self defense".
The wikipedia article says that he was injured and that he got into a conflict with him before shooting. He claims that this was while he was returning to his car and he was attacked by him. If this is true I see no misconduct by him.
