...86% of alerts from citys gunshot detection system led to dead-end deployments, researchers find

An analysis of the citys gunshot detection system released Monday found that nearly 86% of police deployments to alerts of gunfire prompted no formal reports of any crime.

The research, conducted by the MacArthur Justice Center at the Northwestern University School of Law, shows there were more that 40,000 dead-end deployments to gunshot alerts recorded between July 2019 and mid-April an average of 61 each day.

Just 10% of the alerts over that period sent officers on calls that likely involved guns, the researchers found after analyzing records kept by the citys Office of Emergency Management and Communications.

ShotSpotter, the publicly traded company that provides its acoustic gunshot detection technology to Chicago and 110 other cities across the country, claims its system is a highly effective technology thats 97% accurate. During a news conference Monday, Mayor Lori Lightfoot called ShotSpotter an incredibly important tool in our crime-fighting arsenal and questioned whether the new research is actually accurate.

Meanwhile, activists continue to raise concerns about ShotSpotters ability to distinguish between gunfire and other loud noises like fireworks. In addition, alarms are being sounded over the technologys potential to increase the number of highly charged law enforcement interactions in police districts with large minority populations. ...

What about gangsters just randomly shooting off firearms occasionally specifically for the purpose of drawing police away from somewhere else, or just to run them ragged?

While the people are virtuous they cannot be subdued; but once they lose their virtue, they will be ready to surrender their liberties to the first external or internal invader." ~ Samuel Adams 1779 to James Warren

 

Good intentions will always be pleaded for every assumption of authority. It is hardly too strong to say that the Constitution was made to guard the people against the dangers of good intentions.

Im shocked......... you mean very few criminals stand around waiting for the police to show up half an hour later?

 

Sounds like another scapegoat for soaring crime rates.

From the article: 

"The Police Department’s use of the gunshot detection technology has drawn increased attention after the death of 13-year-old Adam Toledo, who was fatally shot by an officer responding to ShotSpotter alerts in late March. Freddy Martinez, executive director of the transparency nonprofit Lucy Parsons Labs, penned an op-ed last week in South Side Weekly calling for an end to the city’s deal with ShotSpotter in the wake of his killing.

“We must work to abolish the use of surveillance technologies to bring justice for Adam Toledo and others like him,” Martinez wrote.

On Monday morning, Martinez’s group and two other nonprofits filed an amicus brief in a pending murder case in Cook County court that relies on ShotSpotter evidence. The MacArthur Justice Center is representing the organizations behind the filing, which draws on the new findings about ShotSpotter.

The defendant, 64-year-old Michael Williams, has pleaded not guilty to six counts of murder stemming from a fatal shooting on the South Side that happened amid a wave of looting late last May. Williams, who was denied bail, already filed a motion April 22 to exclude the ShotSpotter evidence, court records show." 

The system worked so we have to get rid of it?

So you honestly think there is ZERO chance that, the company didn't hire relatives, cronies, those owed political favors, etc, from any of the Chicago Ploiticos that decided yep on the contract?  Please.

It is common for people in positions of authority to seek technical solutions to non-technical problems.

It is also common for people to ignore that technology is usually unable to solve non-technical problems.

ShotSpotter is a technical solution. Crime is a non-technical problem. There are no surprises here.

Good luck finding a recording that accurately represents gun shots, or a speaker that could play them.

It really depends on what the system is actually listening for, sure you won't reproduce an immediate vacinity large caliber gunshot sound, but you could accurately produce a more distant gun shot sould or even a pretty close 22LR sound faithfully...

 

I'm betting the system relies heavily on the actual sound profile vs decibels it hears, I see no reason why you couldn't replicate the sound profile and fool it...

The article says 86% of the deployments for gun shots from the system come up empty handed with no report of a crime, so I would say no.

So the morons post their NY plated cars with these things doing their gunshot noises on Instagram and nothing happened?   :)  No cops came by their houses and asked some interesting questions with ticket books and tow trucks at the ready?

What about somebody using their backyard as a "home theater" with one of those "projectors" that can make a wall-sized image and they are playing a movie that has a lot of gunfire in it?

Could possibly be a disturbance of the peace or noise ordinance violation depending the volume, time of day/night, etc.
