I was thinking about this with flock cameras the other day...what's our actual ROI? Was the world horrible before and these initiatives are going to close a monster crime gap or is this just a giant fishing expedition ... just because?

  Can we cut to the bone a little bit? The recent crime panics are not about a partner assaulting their live-in partner or a random home burglary. There is no real "ROI" to be had.
  It's purely about the unease of living in chaotic cities, the random stabbings, the shoplifting, the visible homelessness etc. Flock is the stopgap here.
  Partly the "feeling" of chaos is just that, a feeling, driven significantly by algorithmic feeds feeding us every random crime from around the country 24/7. Husband murders wife in a murderous rage? No one hear's about it. Mentally ill man murders a woman on the train in a Tier 2 city, immediate nationwide breaking news.
  The other part though is a real dissolution in how we take care of our mentally ill. Complex topic [1].
  I think complaining about Flock is complaining about the symptom. Today we dogpile on Flock to get it cancelled, tomorrow the public will reach for something else. We have to fix the underlying disease, which is a combination of the two factors above.

    Let us also acknowledged that we're living in the safest time in history and modern American cities are extremely safe, despite the unhinged propaganda from the right.

    We can acknowledge that and also acknowledge that a lot of petty crime goes unreported/unresolved because the police can't do anything, and that our target should still be 0 crime and folks are entitled to be upset about any amount of crime. Recent example I have is a work truck behind my neighbors house in the alleyway. Parked for less than 5 minutes, went inside a garage to look at something, came back, and someone had already walked off with their tools. I sort of got the guy who did it on video which I provided to the person who was victimized, but who knows if anything ever really came of it. Probably not. Does that actually show up in crime statistics? I bet it doesn't.
    What is also missing here is that even if there is not criminal activity occurring, there is a general influx of highly anti-social behavior occurring that feeds in to the perception that higher rates of criminal activity occurring. This is very noticeable when you see people casually running red lights, driving without registration, yelling and screaming at people on the street or at the bus stop, and more. Even if I'm unlikely to be a victim of a crime, I don't feel safe when these anti-social behaviors are occurring, people are shoplifting and now going to CVS feels like going to a third-world country.
    Framing this as right-wing propaganda I believe is a mistake and if you are a leftist it just loses elections for you because even if the folks who are concerned about crime levels are wrong (they're not though) the perception matters much more than reality. Denying the perception implies you deny the reality too and fewer people are going to vote in favor of candidates who tell them that what they see for themselves isn't happening.

    So many people's heads are no longer in reality. Perceptions and this fantasy world people have constructed (and right-wing propaganda feeds) is driving election results, not the real world. If you are politician who is part of the shrinking population who is actually still in reality, how do you win? You can't go on TV and acknowledge the phony "high crime" non-reality, any more than you can go on TV and say the moon landings were fake. But, pretending falsehoods are true wins elections. We're in a dark period.

    Do you live in a city? I do. Come to Columbus and stand at the bus stop not a half mile away from my home where people are tweaking out and walking around in the middle of the street, there are piles of garbage everywhere, drivers are blasting through red lights, and everything at the CVS is locked up. Last week someone stole a car and drove it through the best park in the city and ran over a historic marker. I guess it's not a big deal right? We're probably privileged to have a park. Yea? Jeez what were the social circumstances that led these people to steal this car and drive through a park. Society has failed them. It's my fault they did it I bet? That's the message that the DSA and more left-leaning groups are sending to Americans and most are seeing through the bullshit.
    Also your comment about "shrinking population" - you are referring to white Americans right? You're welcome to go look for yourself to see Trump's election results from the last election and see how he increased voter share across blacks and hispanics (and maybe more). How is this "shrinking population" happening when Trump also had the most votes of any president in American history? Maybe the population isn't shrinking in the way that you think.
    If you want to know why Democrats are losing elections despite it being so obvious they shouldn't, your comments and rejection of the reality that many Americans face every day is precisely why. And before you try and accuse me of being some Trump sycophant I have voted for Obama twice, Clinton, Biden, and then Harris and will be voting for Sherrod Brown and Amy Acton here in Ohio. Denying reality because you think that the picture other Americans see must be some right-wing propaganda feed is confusing you. It's simply not accurate. Most Americans do not agree with your point of view. If the Democrats want to start winning elections they better come to grips with reality.

    I think we are just fundamentally disagreeing on what "reality" means. My reality comes from measurement by experts, reports and documentation--hopefully broad, impartial, and highly cross-sectional studies. Yours appears to be about people's everyday perception and lived experience. But lived experience is like looking through a keyhole. It's never going to be complete and applicable broadly. But people believe it's reality because they hear it somewhere or they see a tiny slice of it with their eyes. Your keyhole view of Columbus shapes a broader idea of reality that "crime is rampant everywhere".
    Even if these keyhole slices of reality were not being fed by right-wing propaganda (let's assume for the sake of argument that there is no right-wing propaganda at all), it's still not a reality that is applicable broadly across the country.
    As an example we saw this during COVID. "Nobody around me that I know personally has died of COVID, therefore it doesn't exist, it's a hoax, or it's not a problem."

    Well no I don't think we're disagreeing, it's more about terms that are not captured in measurements, reports, things like that.
    The example I gave is just an example. It's real no matter what the data says. When folks experience that, they experience it and it informs their opinions about the rates of crime and how safe an area is. I can tell you I believe the area I live in is safe, but with the introduction of these anti-social behaviors it is less safe regardless of the level of reported crime.
    I think statistically the numbers show there is much less crime than there has been, but the statistics aren't perfect. For example, can you provide a report or measurement that measures how unsafe people feel when they walk by a pile of needles and have a homeless person screaming at them? If you can't, then you can clearly see there are flaws in the measurements that need to be addressed.
    Chalking it up to right wing propaganda just doesn't help here and only serves to lose votes. I'm not "right-wing". I live in a city. I walk by this stuff. I don't feel safe of comfortable walking by these people. I also don't think my quality of life is improved when I have to go ask someone to unlock a case so I can buy a razor blade or something. If your metrics aren't capturing that then that would explain the disconnect you are seeing.

    That's what my post was about though: You're not really talking about actual crime--you're talking about your own perception/feelings.
    By all measurements and all sources of data available, violent crime has been absolutely plummeting since around 1991. Property crime is plummeting in direct parallel. Yet, nearly every year, a large majority of people (~66% or so) who are polled believe that crime is higher this year than it was last year.
    We measure actual crime and we also poll people about their feelings. The large difference between these two doesn't mean that the measurement of actual crime is flawed. It just means that people are not informed, or if they are informed, they are letting their perceptions and feelings override the actual information. We shouldn't be making public policy based on how people feel.

    But I mentioned other areas where crime occurs but is not reported. It has quite literally happened to me. Crime can be down simply because it is underreported. Here's another example. At my house someone stole a package, I have them on video because they're stupid and that was sent to police and maybe that was solved, idk. But it's quite a bit of work to submit a police report. My local police office has file size limits. I had to go and adjust a video, make sure it's in the proper format, and of course fill out the form, describe everything. If it's a lower value item someone may say forget it, this is too much work.
    Part of the survey response you are seeing is that while crime itself may be down, citizens are uncomfortable and feel less safe (I provided an example that you can come and see for yourself any time of day) and I believe that helps to explain the discrepancy in the data you are seeing. How do you account for increases in crime when someone runs a red light (that's a crime) that simply is not reported? What am I going to do, call the local police? Are they going to actually do anything?
    Data is only just one piece of the puzzle. Arguably not the most important in many circumstances. If the data is telling you crime is down, but people feel as though it is not, that doesn't necessarily mean "right-wing propaganda", and for someone who is inclined as you are to look at data you would think you wouldn't immediately draw such a conclusion and instead you would want to question your data collection process, the methods you are using, whether or not specific groups have stories they want to tell.

    Maybe the majority is right and your data is wrong?
