-based company known for its controversial
gunfire locator service.
ShotSpotter claims it can identify whether or not a gunshot was fired in an area in order to dispatch
law enforcement, though researchers have noted concerns about effectiveness, reliability, privacy, and equity. The company has been partnering with cities and police since 1997, and as of 2022 has been utilized by more than 130 cities and law enforcement agencies in the US.
History
ShotSpotter was founded by Robert Showen in the 1990s while he was working for
SRI International. He created a company in 1996 and tested prototypes in
Redwood City, California. Its early success was described by ''
Wired'' as being "due to good PR, not good technology." James Beldock joined as

location systems for the military; Centurist held a "deceptively simple patent" for the location algorithm. Centurist's CEO, Scott Manderville, became president of the board.
As of 2021, the acoustic locator technology was installed in 125 cities and 14 campuses, covering 911 square miles. The locators are typically installed at 20–25 sensors per square mile and primarily connected via
4G networks (mostly
AT&T and
Verizon). In 2020, Chicago was 18% of the company's revenue, and New York City was 15%.

The company's
gross revenues were $58.2 million in 2021 (increased coverage by 49 square miles and 10 cities), up from $45.7 million in 2020 (increased coverage by 49 square miles and 10 cities) and from $40.8 million in 2019 (increased coverage by 82 square miles and 6 cities).
The company had a net loss of $4.4 million in 2021, in part from nonrenewal of contracts and increases in legal costs, PR from

Toronto, Ontario has declined to use the technology, as the

stated the system "may be of little benefit to police agencies with a pre-existing high call volume. Our results indicate no reductions in serious violent crimes, yet
hotSpotterincreases demands on police resources."
An October 2021 paper in the
Journal of Urban Health, studying the
longitudinal effects of ShotSpotter over a 17 year period, found "implementing ShotSpotter technology has no significant impact on firearm-related homicides or arrest outcomes. Policy solutions may represent a more cost-effective measure to reduce urban firearm violence."
[ ]
The NYU School of Law Policing Project published a paper in 2021, "Measuring the effects of ShotSpotter on Gunfire in St. Louis County, Mo". The paper indicated a significant drop in gun violence in the area. However, the paper also discloses that ShotSpotter "has provided the Policing Project with unrestricted funding".
Jennifer Doleac told
Voice of San Diego that ShotSpotter "resisted attempts (by me and others) to do a rigorous evaluation of its impacts", noting "they’ve clearly found that they can get cities to sign their contracts without such evidence."
Accuracy
As of 2021, ShotSpotter evidence has been used in 190 court cases. ShotSpotter has admitted it manually alters the computer-calculated evidence "on a semiregular basis", and it has never been independently tested, leading to doubts on its accuracy. Vice's ''

'' noted that ShotSpotter "frequently modify alerts at the request of police departments."
''
Associated Press'' also noted their "methods for identifying gunshots aren't always guided solely by the technology."
While the company claims a 97% accuracy, the
MacArthur Justice Center studied over 40,000 dispatches in an under 2-year period in Chicago and found that 89% of dispatches resulted in no gun-related crime, and 86% resulted in no crime at all.
These results were backed up by a subsequent report by the Chicago

, which also found that police officers changed their practice by stopping and searching people for no other reason than that they were in a place known to have many ShotSpotter alerts. ShotSpotter's CEO described an earlier 80% accuracy rate as "basically our subscription warranty," but employee Paul Greene said "Our guarantee was put together by our sales and marketing department, not our engineers."

has raised questions about privacy and surveillance, as the detectors keep hours or days of continuous audio.
This audio has been admitted as evidence in at least one trial and rejected under a
Massachusetts wiretapping law in a 2017 case. When Forbes sent public records requests to agencies in 2016, ShotSpotter sent a memo to all of its customers, detailing how they should deny or redact the requests.
Additionally, the sensors are disproportionately placed in minority communities, leading to more interactions with police, often from false alerts from pneumatic

Individual cases
In April 2017, ShotSpotter was able to locate mass-shooter
Kori Ali Muhammad, enabling police to apprehend him within minutes.
The
Rochester Police Department in New York use ShotSpotter. In 2017, officer Joseph Ferrigno shot Silvon Simmons in the back. Accounts between Ferrigno and Simmons vary, but ShotSpotter initially detected the gunshots as a helicopter. The company reclassified it as three gunshots "per the customer's instruction," then revised it to four shots. Later the company's employee Paul Greene "was asked by the Rochester Police department to essentially search and see if there were more shots fired than ShotSpotter picked up," so it was revised to five gunshots, which put it in alignment with Ferrigno's claims. The jury didn't believe ShotSpotter's evidence, and Judge Ciaccio overturned a gun possession charge, describing the ShotSpotter evidence as flawed. Simmons filed a civil lawsuit against ShotSpotter in 2017, which is still open as of 2021.
Greene also testified in a 2018 case in Chicago where ShotSpotter initially reported two gunshots. On request of the Chicago Police Department, he re-analyzed and found seven gunshots. This matched the police department's account and was not supported by video or
bullet casing evidence.
Another case of reclassification occurred in 2020 with the arrest of a Chicago man for the shooting murder of Safarain Herring. ShotSpotter initially classified the sound as a firework, but a ShotSpotter employee changed it to gunfire a minute later, and later changed the calculated location to match the defendant's known location — over a mile away.
A public defender in the case filed a
Frye motion to examine the ShotSpotter forensic method, and the prosecution withdrew the evidence to avoid scrutinizing it.
The MacArthur Center along with Lucy Parsons Labs filed an
amicus curiae

in the case, supporting the Frye hearing, noting the false positives, the disproportionate deployment, and that "ShotSpotter provides a false technological justification for overpolicing."
The defendant spent 11 months in jail before being released in 2021 when his case was dismissed for insufficient evidence.

Remarking on these privacy concerns, in 2015 then-

William Bratton said "the advocates have to get a life." Bratton had been on ShotSpotter's Board of Directors before then, and rejoined it in 2017.
In July 2022, the
MacArthur Justice Center brought a class action lawsuit against the
City of Chicago, the Chicago Police Department, and several individual police officers for constitutional violations in connection with the use of ShotSpotter. The lawsuit alleges that more than 90% of the time police respond to a ShotSpotter alert they find no indication of a gun-related incident and instead use the alerts to justify scores of illegal stops and arrests. The lawsuit also alleges that Chicago's ShotSpotter policy is racially discriminatory because the system was only implemented in areas with the highest concentration of Black and Latino residents.
Part of ShotSpotter's appeal to privacy is that police do not know the installed locations, which theoretically could allow police to acquire conversations from the ShotSpotter microphones.
Bloomberg News reported, however, that not only were the addresses given to the

, but they relied on the police to help lobby for their installations. NYPD also stated they have also escorted ShotSpotter site survey teams.
ShotSpotter was activated for a shooting at the house of New Mexico Senator
Linda M. Lopez; police were dispatched but did not find evidence.
Design
ShotSpotter's gunshot detection system utilizes a series of sensors to capture loud, impulsive sounds. When such sounds are identified, sensors send data to a pair of algorithms responsible for identifying a location and determining if the event can be classified as potential gunfire. Employees at the company are charged with confirming incidents and notifying local police.
Although it is designed to be just an investigative tool for the police, it has also been used for actual primary evidence in trials, leading to criticism about ShotSpotter's effectiveness beyond its primary purpose.
