Johnson, a first-term mayor, campaigned on a promise to end the use of ShotSpotter, putting him at odds with police leaders who have praised the system.

They argue that crime rates – not residents’ race – determine where the technology is deployed.

And due to decades of racist policing focusing on communities based on residents' race those crime rates are based on exactly that.

This is why police forces love AI; they can feed the systems data based on their own history racist policing and absolve themselves of responsibility when the garbage coming out matches the garbage going in.

That's a bingo right there.

Just an excuse to continue to harass areas that have historically been harassed.

Doesn't make any sense anyway. If I'm Whitey McWhiterson (I am, but if) and I want law enforcement protecting me and not minorities, I'd want this deployed in my neighborhood, right? Or is the false positive rate too high?

[–] lemmdogmillionaire@lemmy.world 13 points 9 months ago* (last edited 9 months ago)

Not only is the false positive rate way too high, they’ve caught the company working with law enforcement to retroactively add fake data points to support raids and arrests.

[–] LastYearsPumpkin@feddit.ch 12 points 9 months ago (1 children)

You don't want that. Because at any given moment, kids are committing all sorts of minor violations. They trespass, stay out too late, get into scuffles, etc.

But now there's a cop watching you 24x7, and catches you smoking at 14 in a closed construction site with your friends... you get arrested cause the cop is a jackass. Now you've got a record, you missed a couple weeks of school, and college won't accept you, and your future is fucked.

You did the exact same thing that millions of other teens did, but because a cop happened to feel kinda like fucking you over, your life is ruined.

You DO NOT want cops patrolling your neighborhood, or anywhere you hang out.

I can't relate. I'll take your word for it but the only shenanigans I got into as a kid was sneaking into R rated movies. Oh I got busted once for sneaking into private property and having sex with my girlfriend. Owner wanted to press charges but the cop talked her out of it because I was 17 and maybe a month from shipping out for basic training. I've never had a negative interaction with a cop.

But you know I'm a pretty fucking boring person. Don't take that to mean I'm on the cops' side when they do stupid shit. I'm just not on team ACAB.

[–] LastYearsPumpkin@feddit.ch 4 points 9 months ago (1 children)

...You realize you are agreeing with me, right? If that cop just felt like it, you would have been fucked, and there was nothing you could have done about it...

That is exactly what happens to minority kids all the time. I'm going to assume you're not black, cause that exact same situation with a black kid would have ended up with that kid not going to basic.

[–] MagicShel@programming.dev 0 points 9 months ago

I never said I disagreed. I said I couldn't relate. I never smoked or broke into construction where I could represent an insurance liability or be blamed (rightly or wrongly) for missing equipment or graffiti. Sounds like the sort of thing a person ought to get in trouble for - white or black. We aren't arguing.

[–] Malfeasant@lemmy.world 7 points 9 months ago

Or is the false positive rate too high?

I'll preface this by saying I have no idea how the system works, but I wouldn't be surprised. I have an old motorcycle that will occasionally get in a mood where it doesn't want to start. If I'm not in a rush, I'll let it sit a few minutes between tries, but if I have somewhere to be, I'll keep fighting with it and keep cranking the starter, which often leads to a massive backfire. I've made neighbors think someone's shooting before.

I want a cop GPS....a little map showing me alternate routes to work that avoid any one cop that may be on the way.

[–] TIMMAY@lemmy.world 2 points 9 months ago

Oh oh I saw this episode of Elementary!

[–] djsoren19@yiffit.net 1 points 9 months ago

*scraps eventually. It's better than nothing, but they are signing a new contract through September of this year, supposedly so CPD can "transition appropriately" for the next six months, whatever that entails.

[–] Rapidcreek@lemmy.world -4 points 9 months ago (2 children)

First you deploy this technology to the areas that you know have been experiencing gunfire. Several microphones are used and when gunfire is "heard" by the server, it can be triangulated to the source location. If you have a video network, you can also move to the source. Guess the server program is not identifying the gunshot frequency correctly.

[–] AA5B@lemmy.world 7 points 9 months ago (1 children)

So we need to know both the range and the false positive rate, as well as the response

  • are they deployed so the only places in range of detection are non-white areas?
  • is there a high rate of false positives that somehow is worse in non-white areas?
  • is the response different in non-white areas vs white areas?
  • does the response specifically target non-white people in the target area?
[–] Kusimulkku@lemm.ee 0 points 9 months ago

I'd imagine there's a higher prevalence of gunshots in the non-white areas so more mics are placed there.

[–] FireTower@lemmy.world 5 points 9 months ago (1 children)

Part of the problem is that there's other loud noises that sound like gunshots like a car backfiring.
