Here Are the Secret Locations of ShotSpotter Gunfire Sensors : privacy

[–] [email protected] 29 points 8 months ago* (last edited 8 months ago) (2 children)

The only problem ShotSpotter solves is not enough public money into private hands. What information does it actually give the police, even assuming that it is 100% accurate?
At a certain time and place a gun was fired. Great? Who cares. That isn't worth $1million/mo.
If there are 3 people in the general location and time that a gun was fired, what has shotspotter done to help?

Fortunately Chicago is getting rid of this finally. https://chicago.suntimes.com/city-hall/2024/02/22/shotspotter-contract-cost-mayor-brandon-johnson-cancel-extension-summer

And, it gives cops another excuse to overpolice Black and brown neighborhoods.

People usually call in shots fired. So all they've done is create an expensive device that maybe tells them a bit sooner than a concerned citizen.

This is where I disagree. I think a transparent, publicly run system to triangulate gunshots is actually a great idea. As long as the microphones are placed evenly throughout a city, they can instantly let police know where and when a gunshot happened.

However, with no way to publicly verify the fairness of the a private system, there's only one way this could go.

Doesn't triangulation get fucked up by the presence of buildings? I don't imagine these give much more precision, even in the ideal situation you describe.

[–] [email protected] 1 points 8 months ago

I imagine that theoretically you could have algorithms or machine learning to calibrate this. Like make test sounds so you see how the sound diffuses and then filter it out.

Maybe I missed it but the article actually does not tell/show you where these secret locations are. A red dot on a map that doesn't zoom in well enough is kinda useless.

Article tells you it all.... if you know where to go! (was just sitting in the JS)

Document expires in 5 days (March 1st)!

[–] [email protected] 2 points 8 months ago

I kept the default expiration.

The data there is what was in the JS. I just pulled it out and ran it through a formatting tool so it can be consumed more easily by humans.

Whether the mics would pick it up would depend on if you use supersonic bullets. They would sense that they are shutting off for some reason though.

Edit: If you shoot one but another is in range to pick it up then it would. This is starting to sound like a cs problem.

Can we zoom in on the sound and enhance it to triangulate the shooter's IP address on the Unix mainframe?

Youll need to write a gooey in visual basic first

If two of us type at the same time on the same keyboard, we can work twice as fast!

[–] [email protected] 5 points 8 months ago (1 children)

Well, the bullet will travel faster than the sound of the shot so no

[–] [email protected] 1 points 8 months ago

Depends, some loads are subsonic especially for suppressor use. I'm looking at you, 300BLK

[–] [email protected] 4 points 8 months ago

Probably not, since there has to be some processing of the noise to identify what it is. TheBackyardScientist did a video somewhat similar to that, here: https://piped.video/watch?v=4WSQqDHK1Yw

[–] [email protected] 2 points 8 months ago (1 children)

That's what suppressors are for

[–] [email protected] 2 points 8 months ago

Suppressors aren't movie quiet, they just bring down the noise to make it hearing safe.

This leads me to wonder, would a suppressor actually trick these machines, does it have to be supersonic to pick it up?

And, what happens when someone near a sensor needs a new roof? Roofers constantly harassed by cops? "Not allowed to use .22 cal nail guns?" Would this thing not pick up Ramsets?

Muricans do everything but forbid guns
