Having some experience with firearms, I know that training is crucial.
My first teaching job was in the White Pass School District in Eastern Lewis County, WA.
There were a couple of gas station "supermarket" combos and a small movie theater in Randle, Washington. Move night was Thursday. There had been a cable system, but people stopped paying for it, so there was only one Seattle station that you could receive all the time, At night, if the weather permitted (and usually it didn't) you might see a couple more stations. It rained a lot.
A major social occasion was going down to the town dump and shooting rats. And the band teacher has a six shooter, so practiced a bit on weekends. The rats were large, but speedy, and Randle was in a valley so after 3:30 PM or so, the Sun did not illuminate the area well at all.
