This makes sense.
I lived for several years in New Orleans, behind Wagner's in the Bywater. In 2022, it was ranked the 8th most dangerous city in the world. The gunfire was constant. Anyone who knows that corner knows the Family Dollar was so riddled with bullet holes that they eventually stopped repairing them. I'd be enjoying my morning coffee in my backyard, sitting on my bench with the neighbor's calico meowing at me, when fully automatic gunfire would ring out. I'd go to the Facebook group page, where people with military or gun experience would identify the type and caliber of the weapons involved. Then came the pictures of people's cars sprayed with bullet holes, and a story about someone lying in bed when a bullet whizzed over them and hit the opposite wall.
That intersection has cameras everywhere! The police already know what happened. If someone wasn't murdered it would hours before they would come out and look.
When I first moved there I lived in mid-city by 12 Mile Limit. Before I arrived, there was a triple homicide. Then there was a double homicide. The building on the corner had video of everything. They ended up towing the owner of the building's truck because it was evidence. She went to the impound to get it back because the bullet hole was from the previous triple homicide.
During these incidents, which are often (getting better over the last couple years), hundreds or thousands of people can hear them. The sound of fully automatic guns can carry for blocks. Being able to handle all the calls focusing on the few that arrive first likely will improve the service.
