"...even if you have astonishingly low gun crime in Europe...." Er, no. You have astonishingly high gun crime in the States. Sorry 'bout that.
Our gun crime rates per gun are flabbergastingly low. Our gun crime rates per capita are excellent, except in some of the largest cities.
I think I'm going to start reporting our bug resolution counts by text editor.

> astonishingly low gun crime in Europe, making the exercise a pointless waste of money Worse than that; if you listen long enough and carefully enough, you will hear gunshots. It's like over-used medical testing: look for a problem, find a problem, treat the problem, even if had you never looked the patient would generally be better off.
Rural Canada here, in an area with no real gun crime. There are people on their farms shooting things (rabid animals), or hunting in season. I guess you could only use these things in downtown of a city, otherwise so many false positives.. I can't even imagine in the US, land of 7 guns per person, plus of course the dogs are even armed...
I don't really care if "rural people" are using guns but to claim shooting rabid animals is a major use-case is wrong or initially misleading.

Yeah for the past decade I’ve had awesome results by not doing anything during a controversy, and then sending DMCA requests and other digital cleanup methods to every source a few weeks later The idea was that people’s system caches would have deleted stuff by then, so anyone that noticed at that point couldn’t go resurrect to attempt to start a Streisand Browsers and the internet are super different now, but the sa…
You can only issue a DCMA request on behalf of the copyright holder. There is no takedown for butthurt.
People don’t really care that much about their Streisand hopes to argue fair use or bother
But the presence of material makes it a legitimate DMCA request (not like legitimacy is enforced, but I cover my own bases at least)

That's just replacing their anecdotes with your anecdotes. Why not look at actual data, which is likely to tell you that crime has plunged everywhere since the 80s.
Did it plunge though, or did people stop reporting, and police stop taking reports? Do we know why it plunged?
Genuine question though, can one get accurate/precise triangulation from microphones? This isn't comparable to Richter scales distributed across the land to measure locations of earthquakes. Are we dealing with sham tech?
The biggest problem are reflections and multipath (which are also problems for locating earthquakes). Also, classifying whether a noise came from a gun, when heard from far away in an urban environment with lots of other noises around, is hard.
Simplest method is trilateration. By knowing the travel time from multiple places, you can figure out the source point.

Sound waves travel 300m every second.
If you can get devices synchronised to 1ms (which isn't very difficult given very easy access to GPS which is orders of magnitude more accurate), you can triangulate to at least within 1m.
There is some complication like the sound travels at different speed depending on pressure of the gas. The sound might have also arrived to the microphone on not the shortest path. The shortest might have been obstructed, for example, and what you got is a reflection off of a distant object or even sound that was "bent" by layers of air with different properties.
But if you have ever heard a gun shot, most of the time you got first the sound wave that reached you directly and then possibly some reflections. By analysing those reflections and assuming that if multiple gunshots were made, they were made at roughly the same spot, it is possible to discern whether you heard one gunshot with reflections or multiple series resulting from multiple shots.
