You're telling me that cities are picking minority areas to put these in just for ill intent? Also, the devices don't "enforce crimes", they only alert approximate areas where a gunshot/firework may have gone off at.
They didn’t comment on motives, just on reality. That is where these systems are deployed.

#114(Not the OP) For background, this is the company that supposedly locates gunshot sounds in cities (and sometimes battlefields) by microphone triangulation. It doesn't work all that well and is selectively deployed in minority areas and is used by police to selectively enforce crimes, sometimes also altering the evidence. Vice did a few articles on them and the company tried to sue but had it tossed out. Shady all aro…

I dunno if this company deserves that benefit of the doubt. Honestly, given their history, they probably just don't want to reveal that their entire business is snake oil, basically existing solely to make money by enabling law enforcement to create crimes out of thin air. If their science was sound they wouldn't have to resort to such tactics...
Why are you so skeptical of their technology? Look how accurate raspberry pi powered ADSB plane tracking networks are — and that’s a much harder problem: they have no funding, they’re doing triangulation at the speed of light, and they’re doing it without GPS clock sources. You could also point to the lightning tracker networks that work in roughly the same way. Given a few million dollars to outfit their nodes with…
I'm skeptical of this company in particular. See this other comment: https://news.ycombinator.com/item?id=32259253
Edit: I think a novel implementation here is that they often use one mic array (several mics mounted around one tower or vehicle) as opposed to a dispersed network at them. If they made that work effectively, I think IMO it's different enough as to be novel and patent worthy. But it also strikes me as the kind of technology that should be defensible on its own merits, and legitimate copycats easy enough to identify, rather than blanket squelching tactics and going after journalists. That's what snake oil salesman do, not companies with actually superior technology. Read the Vice reports. Their effectiveness record isn't great except in their first party sponsored research.

If I’m understanding your reply, you seem to think that it should be obvious to anyone with an understanding of how guns work, that this idea wouldn’t work/isn’t feasible/is a bad idea in some other way. So, wouldn’t it be more productive and informative to state that opinion and support it?
Further, this loud tone would require enough power that you’re talking about replaceable batteries. Those batteries can be removed.

Jackson MS uses shot spotter and is 80% black, and no, they aren't deploying it in predominantly white "minority" neighborhoods.
Do you seriously think by "minority" they meant at the local populace level and not national populace level? When has that ever been the colloquial use?

In ADS-B, planes broadcast their locations.
MLAT time-difference-of-arrival improves the accuracy substantially. Edit: not true, but can provide equivalent accuracy. https://www.flightradar24.com/blog/how-we-track-flights-with...
