What happened

Detroit Police Chief Todd Bettison says alerts from ShotSpotter, a gun detection technology, help officers respond quickly to shootings.

Why it matters

“Without it, I wouldn’t have the closure rate [of resolved crimes] that I have and a lot of families wouldn’t have the justice they deserve,” he said in March 2026, according to BridgeDetroit, a nonprofit news service.

Common ground

During a Detroit City Council committee meeting on May 18, 2026, police officials said ShotSpotter led to hundreds of search warrants and confiscated guns in 2025.
