The Cambridge Police Patrol Officers Association (CPPOA) is deeply disappointed by the City Council’s vote to eliminate the use of ShotSpotter technology in Cambridge. As the union representing nearly 200 police officers sworn to protect and serve this city, we must question the very commitment of the City Council to public safety.
This decision threatens to make Cambridge less safe by slowing emergency response to gunfire. ShotSpotter has been part of Cambridge’s public safety infrastructure since 2014. Removing it now sets the city back more than a decade by eliminating a tool that alerts police to likely gunfire within seconds — including incidents when no 911 call is made.
There is no credible evidence that ShotSpotter has been used to monitor private conversations or identify individuals. Its purpose is narrow: detect likely gunfire, locate it quickly, and help first responders act faster.
Cambridge Police Department leadership identified at least 11 instances in which ShotSpotter detected gunfire when no corresponding 911 call was received. Those are not abstract statistics. They represent real moments when officers and emergency medical personnel could have been left unaware of possible gunfire, delayed in responding, or unable to provide lifesaving aid.
At a time of heightened concern over gun-related incidents, such as the recent shooting on Memorial Drive, Cambridge should be strengthening its ability to detect and respond to gunfire, not weakening it.
The people of Cambridge deserve public safety decisions that improve emergency response. Unfortunately, the City Council has voted to make it harder for police officers and first responders to know when and where help is urgently needed.
