Same here, I live in a small suburb on the edge of a metro area of 2 million. If I hear gunfire, things have gone bad. Thankfully, never have.
True story... Back in `93, I was fresh out of the military and drove my musclecar across the country to Marshalltown, IA to visit my best friend from the Navy for the summer. I brought a girl with me and I moved in with my buddy and another guy, and she rented a small apartment near the downtown area.
Marshalltown was maybe 20k people back then and a picturesque Norman Rockwell Iowa town. My girlfriend called me one night around midnight and said she heard gunfire and was scared.
Whatever. Pretty sure she was exaggerating and was just lonely. So I drove the mile or so from my place to hers.
As we lay in bed, about half an hour later, sure enough, I heard pistol fire. Then another few minutes, a couple of more shots. Probably about 1/4 mile away or less, and coming from the West, which was a rundown neighborhood.
The day, I reported for work to a general contractor and asked a co-worker, who had grown up there, about the gunfire.
He replied that the local meat processing plant employed a large number of south of the border citizens and the crime was getting out of control. He had a buddy that was a cop and told him that the police chief, mayor, and the local paper conspired to suppress the actual number of crimes going on in the town. He said if the citizens actually knew how many murders, rapes, and other violent crimes occurred in their little town, then there would be a lynch mob to shut down the plant, which was the largest tax payer in the town.
It was surreal. It was in that town that I had to rescue that girl from a laundromat at gunpoint from a group of young Hispanic males.
So yeah, if you hear gunfire in town, then things have gone sideways.
