LAPD stands by its predictive policing software. But cops don't.

Tattoo shop owner Edward Everett shows LAPD Senior Lead Officers Denise Vasquez, center, and Oscar Bocanegra where cars have been burglarized on Sherman Way in Reseda. The officers patrol where a computer program predicts property crimes will occur.

“We tested the software and eventually subscribed to the service for a few years, but ultimately the results were mixed and we discontinued the service in June 2018,” spokeswoman Katie Nelson said in a statement. Los Angeles Police Chief Michel Moore says a data program that predicts locations of property crimes is a useful tool. intended to identify individuals most likely to commit violent crimes and announced he would modify others.

“It never panned out,” said Rodriguez, who spent 11 years with the LAPD. “It didn't really make much sense to us. It wasn’t telling us anything we didn’t know.” UCLA anthropology professor P. Jeffrey Brantingham, who helped develop the software and co-founded the company, said the technology behind the program — data-crunching and geo-mapping — is sound.The Hagerstown, Md., Police Department canceled its $15,000-a-year software service in 2018 because of budget constraints, Chief Paul Kifer said.

While other departments have spent money on the software, the LAPD made its first payment — $50,000 — this year for server maintenance, he said. The department recently began posting the maps online and sharing them on social media — publicity that in itself may serve to deter crime. “When there is a lull in action, you are expected to be in the areas,” Embrich said of officers. “We’re targeting where the crime is. It’s paying off for us. Their presence is a deterrence to crime.”

As the duo cruised through residential areas, they scanned yards between houses and alleys for suspicious activity.On commercial corridors, officers also walk the streets to talk to business owners about what could be driving up crime. In the West Valley Division, burglaries and motor vehicle thefts rose 3% and 9%, respectively, from April to May, records show.

“It’s very, very valuable to have police in a high-crime area,” he said. “If it gets them in certain areas between answering calls, it helps. The visibility absolutely helps.”But the use of complicated algorithms for data-driven programs like PredPol makes it difficult to evaluate their overall effectiveness in targeting crime. Since the programs forecast risk, much of their efficacy is in crimes never committed, some police officials argue.

Minority report!!!

You're using the data wrong. Ask better questions of the data

Because they dont have the space to house all the would B criminals.

So the civil liberties groups are complaining it adds to more policing in black & latino neighborhoods.... So basically the areas with more crime... (I never heard anyone say ..this was a great neighboorhood til those white people moved in) smh

Who has it come under fire from ... I bet it's the aclu & the 'left' basically the people commiting the crimes.... Why would they possibly want to be safer...

IDreamIn4D Thus sounds like minority report! Wtf? Talk about people getting arrested for nothing. Gtfo!

BrianTabatabai How about a software w an algorithm designed to show where to increase educational funding, job creation, free child care, and free tuition. A software to teach cops how to interact w minorities WITHOUT killing them. A software that keeps body cams running and prosecutes bad cops

Talk to me when they figure out a way to predict future bad cops, racial profiling and unnecessary force. Until then... criminaljusticereform

minority report

mktwalker 🤔🤔

lapd predict these nutz

Me using data technology

I actually met that dude, he's a tattoo artist in the sf valley

RikeFranke Ulrike, there is a German system called „Precobs“. We have had good experiences with it in the canton of Baselland, Switzerland. Other cantons do not want to procure it because they see no improvement (or because they shy away from the costs).

sonaliranade Agatha predicted too many alternate situations?

The left doesn't want to predict and thereby prevent crime because it might interfere with the self-realization of criminals -- who after all are just carrying on a guerrilla war against an unjust society. Am I doing this right, ?

So he had two fried tamales for breakfast, then sent cash back home to El Salvador. Let's bust him. Yeah sounds legit.

Is that some of Bratten's leftover nonsense?

Common sense, if you keep screwing over people it usually is just passed on to the next innocent victim, stop it at the source, make the state grow up and quit playing victim, it's time to bring charges of crimes against humanity for those involved in this drug war

Pre-crime is here, awesome. Use it in BH and rid us of miscreants LAPDHollenbeck

Go on strike and stop getting shit on so the citizens will really appreciate you guys.

but are we surprised old habits die hard. it takes influence to change minds and collaboration between society, technologists, and the government to *actually* make change happen.

Wut

Kind of reminds me of COMPSTAT.

LAPD pioneered predicting crime with data. But many police don’t think it worksThe widely hailed tool the LAPD helped create has come under fire in the last 18 months, with numerous departments dumping the software because it did not help them reduce crime. what a scam. Crime hotspots are crime hotspots. It doesn't vary. Another waste of tax money. Guess they have to go back to actually working with the community.
