You'd have to also be careful about the statistics because "getting shot at" and "being involved in a shooting" could really be messed with.
Precisely.
In my career, I discharged my weapon once, killing a Great Dane that the owner had sic'd on me. Not the dog's fault, but what are you gonna do?
On the other hand, I have been shot AT numerous times, but either:
1 - Could not locate the source of the shots.
a - Walking down the sidewalk in the projects, someone opened up on me and my partner. The rounds hit the wall around us, about 20 rounds, but we could not identify the source and engage before the guy just disappeared into the darkness. Multiply this incident numerous times.
b - Took rounds in the helicopter twice. Once we could see muzzle flashes and knew we were getting shot at, once we found the hole in post-flight inspection.
2 - Could identify the source, but could not engage
a - Guy shot at us during a riot, but he was in the middle of the crowd and we could not return fire. Two incidents like this.
b - Gunfight between the dopers and Hell's Angels, during which one member came out on the HA House balcony with a rifle sniping dopers. We got there, and he shot at us, but with pistols and shotguns and a large open area in front of the house, we could not effectively engage him. Once SWAT snipers got there, he gave up.
c - Two robbers shot two officers and ran into a wooded area. We attempted to track them, but they were shooting at us with rifles and we had pistols and shotguns. They were able to drive us out of the wooded area, but could keep them contained until SWAT went in and got them.
Police get shot AT a whole more more than they shoot back.
