What makes it particularly galling is that they also oppose automated enforcement of traffic laws. Officially it is because it would take away jobs (that they are not doing, since traffic enforcement in NYC leaves a lot to be desired), and unofficially because the police themselves benefit from the discretion exercised by fellow officers refusing to enforce laws on their colleagues.
Getting rid of the job gets rid of the people with experience, so it can be a one way switch.
Normally solving a problem with a robot creates more jobs. There are speed cameras, but still you have hidden manually operated speed traps and it frees up resources for drug and alcohol testing.
Propaganda will make sure this won't even reach the average citizen.
There was an attempt to defund police, and that went down with the electorate like a lead balloon.
It's the moralizing religious right and the jackbooted ivory tower left types (both of whom think they know exactly how other people should live) that want lots of policing.
Because a capitalist economy is rooted in self-interest. Labour bodies have power to shape the economy, and they represent the interests of their members, who don't want to lose their jobs.
Plus, people are not perfect market actors with such little empathy that they are willing to abandon their colleagues for a bit more workplace efficiency. So if you know that Bob in your office will be fired due to automation, and you like Bob (and worry you are next), you're going to oppose automation.
Watch an open-air market for stolen goods. Watch the impunity. See how City Hall and SFPD respond. https://youtu.be/dykaJjegDEY
There is no suitable excuse for this, at all, full stop.
I mean... what the fuck is that "yeah we have so many leads to follow up". Dude. Take a hundred officers, cordon off the area and fleece everyone. It isn't that hard. And what the fuck was that "we want police to focus on bigger things"?! Like, camera crews get robbed on highway heists? At gunpoint? Doesn't get much bigger than that!
history of police: the NY police force stared when one politician got his street gang made official.
So the police have a cultural heritage.
And on the other side,the city isn't a bunch of people who basically agree (or think they basically agree) on what is right and wrong, then use the law to enforce this. Counter-example, Sweden from circa 1000 to 2000 AD. (Sweden still thinks it is this, but has growing issues with immigrants from non-nordic cultures)
