>the cops legitimately thought someone was shooting at them But cops always "legitimately" think someone is shooting at them. Have you heard of the acorn incident?
Forty-seven officers were shot and killed in the line of duty in 2023. That's about 1 a week.
Something along these same lines — I feel like I’m seeing those “Flock” cameras everywhere now. So between Shotspotter and Flock, you’re pretty much always under surveillance.
I've considered filing a FOIA request about them but can't figure out quite what I'd be asking for. Data retention? Frequency of queries? Efficacy?

ShotSpotter is recording conversations inside peoples homes and on the street. You can definitionally hear someone making a drug deal or talking about the joint their smoking etc. I'm reasonably concerned that once recordings exist getting access to them is much easier, especially as police have already heard many conversations taken from these recordings.
Can you point to an example of a ShotSpotter sensor recording a conversation inside somebody's home? That seems unlikely given that these sensors are installed outdoors.

Police presence increased the detection of crime and thus increases the statistics of crime in the area
So the bodies of people shot are seen more often in high police presence areas and just not found in other areas? That seem strange that it would be due to higher police presence. The fact that for non violent crimes the stats are skewed sound plausible but that seem less so for violent ones.

> less than five percent of cases Wow that's even worse than what I had read from reports about the deployment in Chicago (which I read up on when Seattle was considering it). I think the value was like 10%. Chicago also ditched it recently I think.
> Chicago also ditched it recently I think. Kind of. The mayor said he was shutting it down for not being effective. And then he went and renewed the contract until just after the DNC convention: https://chicago.suntimes.com/city-hall/2024/02/22/shotspotte... My read is that they know it does work but they don’t want to continue to use it because statistically the “wrong” people are committing the crimes it’s tipping…

This sounds an awful like it is saying the solution to crime is to gentrify? What happened to the communities in the study? If you suddenly increase property values in a community where almost everyone rents, guess how many can afford to stay?
If that's what it sounds like, I'll hazard a guess that you never made it to the research.
I have some noisy neighbours and I've thought of the same idea for controlling noise in neighbourhoods. You could have a microphone on every lamp post and send people fines for violating the rules.
I've been having a nightmarish time trying to track down intermittent low frequency industrial noise. It's over the EPA regulations, it's neighborhood wide, and it is on for 2 hours between 11pm and 1am on random days. The EPA did monitoring of the house and site but couldn't pinpoint where it was coming from because of how low frequency it was. This isn't surveillance, this is the equivalent of finding who is dumpin…

Buy a whole load of the same model voice recorder, label them with tape for location, spread them out and record till batteries die, pull data to PC, repeat until get a sample? Someone above mentioned microsecond accurate clocks on raspberry pi being used for TDOA.
I think it's lame to limit the detection to just gun shots. Like the web has analytics, I think real life could have audiolytics. One example: I can collect all the data I want from my backyard and give a report to my neighbor about exactly how long and how loudly their dog has been barking. I can hear which birds have been in my backyard. I can... hear what a customer says about my product in-store and offer them co…
Automatic localization. The techniques of training the model would likely be the same or similar for other similar sounds.
I've also been blogging about ShotSpotter and review the evidence that the system is good or bad. https://quickthoughts.substack.com/p/shotspotter-good-or-bad There's a lot of evidence that ShotSpotter detects almost all gunshots and that's been validated by multiple third party groups. ShotSpotter also seems to alert to things that are either false positives (construction sounds, fireworks, etc) or are not useful. C…
