Study Questions Accuracy, Utility of ShotSpotter Technology Chicago News

The Chicago Police Division’s use of ShotSpotter, an acoustic gunfire detection system, has come into sharp focus in the latest weeks, particularly after 13-year-old Adam Toledo was fatally shot in March after an officer responded to an alert of expertise .

A new study by Northwestern College’s MacArthur Justice Center found that 86% of Shotspotter alerts did not report any crime or incident to the police, resulting in questions about the value of expertise in violence waivers.

On Monday, a coalition of nonprofits represented by MacArthur Justice Middle filed an amicus curiae in a pending murder case that relies on Shotspotter evidence.

The “Black Voice” invited Shotspotter and the Chicago Police Division to interrupt dialogue. CPD did not respond to our request; ShotSpotter declined and sent the next statement:

“ShotSpotter’s highly skilled expertise, with a 97% accuracy score nationwide, serves to rapidly assist gun violence victims for regulation enforcement, reduce violent crime, bring peace to communities affected by persistent gun violence.” is an important tool.

“ShotSpotter expertise is extremely accurate, alerting authorities to the exact location of gunfire incidents in less than 60 seconds, finding victims who seek help, getting medical help quickly, saving lives.

“Nationally, more than 80% of bullets are not reported to 911. Our expertise fills holes in Chicago and 110 other cities across the U.S. to deploy officers to crime in real time, saving lives. helps.”

MacArthur Justice Middle Legal Professional Jonathan Mannes says it is unclear what “correct” means in relation to the shotspotter.

“I don’t know how they get the accuracy fee when we found that 86 percent of the time, they get no evidence of any crime or other reportable incident,” Mans said.

“We know that ShotSpotter has never completed a properly validated test to see how the system is typically triggered by issues such as firecrackers and development noise, so it seems to me that it is quite possible that these From many of the alert systems responding to the different sounds we make in a metropolis like Chicago, they’re usually just sending the police out thinking there’s going to be gunfire, when most likely not.”

Freddy Martinez, director of the Lucy Parsons Lab, says his group’s ideas with ShotSpotter surpass its claims of accuracy.

“ShotSpotter doesn’t exist in any majority-white neighborhood, clearly we all know it’s not like there’s no gun violence in these neighborhoods,” he said. “So what happens is that you have law enforcement officers who are thinking that there are shots fired, running to the place where black and brown people are walking around, and really only thinking that everyone is armed with a gun. This is suspicious. Had it not been for him, the child might still have been alive at this time.”

Artinees Myrick, a mass organizer with the religion-based group Reside Free Chicago, says people she works with in communities where ShotSpotter gear is located don’t find it effective.

“We’re still dying when law enforcement officers come to the scene. ShotSpotter does nothing but monitor and monitor black communities. It doesn’t … make them safer,” Myrick said.

While ShotSpotter’s experiences resulted in more than 5,000 police experiences, that quantity doesn’t justify its use or expense, Manes said.

Lucy Parsons Labs was one of three non-profit organizations that filed an amicus transitory request to Cook Diner County to exclude shotspotter evidence from a pending homicide trial.

“We now have scientific requirements for evidence that needs to be included in a court case,” Martinez said. “One of the many arguments we make is that this evidence does not match a scientific general … if it is flawed 9 times out of 10 we would not need to include the DNA proof.”

And in regards to spending the amount of cash City has to use ShotSpotter, Myrick believes it will be spent elsewhere.

“$33 million is pretty low to invest in a black group,” Myrick said. “It could very well be allocated to preventive services, holistic psychological health services, hospital-based services – focused policing has not been seen to discourage crime or keep people safe. That $33 million could go to preventive companies that will undoubtedly save lives.”
