Earlier quoted context omitted.

Do they?

Even in Baltimore where police response times can be total garbage..they will show up for shot spotter. At least from my experience. Calling 911 for anything else there is a long delay unfortunately. Last time I called for a car jacking right outside my home I was on hold for ten mins. Cops didn't arrive for another 20.

I can't help but think how easily such a system - which is hardly sophisticated, in technical principle - could be used to pinpoint things that are 'problematic' in my neighbourhood. Loutish vehicle behaviour of various kinds. The loud Harley Davidson and dirt-bike signatures associated with the comings-and-goings of local gang members. Squealing tyres of deliberate burn-outs on the road. The occasional fool loudly blasting down the road at twice the speed limit. Things which the current system of "wait until someone gets annoyed enough or gets the courage to call the police to complain, and one might arrive 15 minutes later, by which time the coop has been long flown" allow to run mostly unchecked.

But those thoughts go hand in hand with a vague but distinct discomfort.

To give ABQ police the benefit of the doubt, that pattern could also be compatible with more gun crime equaling more surveillance. It would be nice to have enough gun crime and sensor location data to see how true that is. When the sensors…

It sounds like shotspotters are likely to be near where shots are; and that the wealthier you are the more likely you’d NOT want to be where the shots are.

I've experienced living in a neighborhood covered by shot spotter and hearing gun shots outside, and I think shot spotter is great. I want the cops to actually show up and arrest whoever is terrorizing everybody. Thank you very much

Has having ShotSpotter in your neighborhood increased the safety? Is there faster response? higher arrest rate? decrease in crime?

In Chicago they will respond to them aggressively . Gang members have figured this out and will have “decoy” shots fired before a hit takes place to tie up police.

I'm curious if the author lives in the wealthier or non wealthy region.

I do not own a gun. I currently live in a city and would be happy to learn they were installing shot spotter near me.

It's maybe the least intrusive type of surveillance there is. It just says a signal if there is a loud noise in public.

If anyone wants the raw data, it's available in window._Flourish_data variable on https://flo.uri.sh/visualisation/16818696/embed

Which means you can extract it with my https://shot-scraper.datasette.io/ tool like this:

    shot-scraper javascript \
      'https://flo.uri.sh/visualisation/16818696/embed' _Flourish_data \
      > /tmp/data.json
That's a 25MB file.

I loaded it into SQLite like this:

    cat /tmp/data.json | jq .events | \
      sqlite-utils insert /tmp/shots.db locations -
Then opened it up in Datasette with https://datasette.io/plugins/datasette-cluster-map to see them on a map.

Also

Chicago is letting the ShotSpotter contract expire instead renewing this year after the data revealed that it did not have any positive effect on crime reduction.

> more gun crime equaling more surveillance

But if you're not listening for the guns then you're not going to find the crime that does happen, will you? It's either saying "we don't care about it because it's less frequent" (which is stupid—you still build a fire station in places where buildings burn down less frequently) or "it's easier to keep ourselves busy when we fish in a barrel".

There's an interesting control system feedback complaint with a lot to it;

* historically there's been a lot of "black crime" in the US due to the US police watching black neighbourhoods excessively and being absent elsewhere .. take this all the way back in time to Tulsa and before.

* Subsequently there's been a lot of "black crime" as neighbourhoods have been destroyed by occasional mobs (Tulsa), frequent division by freeways and toxic waste dumps, and the removal of many adult males to the prison system as a result of all the "observed crime" leading to an excess of young males with few prospects.

* Based on that data the modern survellience goes to where all the crime has been created^H observed.

Meanwhile entire areas of US cities get on by considerably less police present and oversight and a great deal less observed crime.
