Birmingham debates effectiveness of ShotSpotter gunfire detection system
Birmingham's use of the ShotSpotter gunfire detection system is under scrutiny as the city grapples with rising gun violence.
When a shooter littered 5th Street South with two dozen shell casings last week, Birmingham's gunfire detection system triangulated the exact spot within a couple of feet.
Lawrence Billups first came to work for the Birmingham Police Department in the early 1990s.
Back then, pinpointing gunfire was a little less exact.
"If you heard it, you heard, but you couldn't pinpoint where it was the cause of an echo. And so you would just be riding around," said Lawrence Billups of the Birmingham Fraternal Order of Police.
"Could be half a mile away," added 米兰体育 13's Jon Paepcke.
"You can be a half a mile away," Billups confirmed.
In 2007, Birmingham hired ShotSpotter, a company that uses sonar technology to track gunfire in select neighborhoods.
Since then, the system's coverage area has more than tripled in the city.
"It allows you to get to the area where there were the situation taking place quicker," Billups said.
However, some of the nation's largest cities are questioning the system's law enforcement value.
In June, New York City's comptroller released an audit criticizing ShotSpotter's accuracy.
"During the sampled months of review in 2022 and 2023, ShotSpotter alerts only resulted in confirmed shootings between 8% and 20% of the time," the audit stated.
ShotSpotter responded by touting a 90% accuracy rate, arguing that the comptroller's "methods of verifying gunshots are more suited for an episode of 'Law & Order' than they are for the realities of policing."
Mayors in Chicago and Houston also plan to discontinue the service.
"Should Birmingham do the same?" Paepcke asked.
"No, no, it's a necessary piece of equipment that we need," Billups replied.
Since 2007, Birmingham has spent more than $9 million on ShotSpotter sensors, including nearly $1 million annually under the current contract.
Despite this investment, fatal gun violence in the city has skyrocketed.
Since 2019, Birmingham police have investigated nearly 800 murders.
"I don't think that ShotSpotter was ever made to solve homicides. I think that it's made to alert the police department about a location of either gunfire going off or something else happening, like fireworks," said Birmingham City Councilor Hunter Williams.
"It is well worth the money. We've been able to catch people in the act of shooting," Billups said.
To demonstrate the technology's effectiveness, records of any arrests or gun confiscations linked to ShotSpotter dispatches in Birmingham were requested.
However, the Birmingham Police Department stated, "BPD does not track that kind of data."
米兰体育 was told that they do use the system to decide where to place resources and solve investigations.
"The officers out here, they love it because, like I said, it takes a lot of the guesswork out of trying to find out what, where the shots are coming from," Billups said.
When officers quickly arrived at the 5th Street South scene, they did not find a victim, and the shooter was already gone.
