Officials with the city of Mobile say the new ShotSpotter system is working. The system pinpoints the location of gun shots using network sensors and software.

"If you look at where we were since we started back through January, we were looking at almost 3,900 rounds fired and if you divide that up sort of over a period of time, we're seeing a significant decrease in each quarter that goes by," Kevin Levy said, a Commander in the Mobile Police Department's Intelligence Division.

NBC 15 has continued to check in with Levy every couple of months to see how ShotSpotter is working. Since the last time we spoke with Levy, he said they're seeing two things.

"Where as before we had almost 1,500 rounds a quarter, but now we're at less than a thousand rounds a quarter," Levy said.

Which sounds like a lot, and it is a lot. However, Levy said it's progress. Calls to 911 are also improving.

"Our 911 calls for incidents where there is gunfire has increased significantly," Levy said. "Last year we were sitting around 4%, right around New Year's we were pushing around the national average, around 16 or 20%, now we're almost close to 30%."

But Levy knows that these are just numbers and they're not intended to make anyone feel better.

"This is what you really get when you look at the raw data," Levy said. "Before we had a gun shot detection system, we didn't really know what was happening, we only knew what was reported. Now we know what's happening, and what's being reported and we're seeing a reduction in what's happening and an increase in what's being reported."

ShotSpotter is part of Mobile's Operation Echo Stop in an effort to reduce gun violence in the city.
