I belong to a gun club and it's a running joke about the police's poor shooting ability. Police officers tend to be reluctant to practice because they don't want to spend the money for the ammo!
That is the truth. I worked one summer for the Atlanta PD and used to go to the range with the guys in our precinct. Except for one guy who was also a gun collector and competitive shooter, I could outshoot them all with my mom's little .32 revolver (and it's not a very accurate piece - strictly a nightstand drawer item. Dad bought it for mom when there was an escaped convict sighted in our neighborhood, one of my earliest memories is of my mom pulling it out of her purse to put it away . . . ) I was all of sixteen at the time, although I did have all my little NRA medals from summer camp, it wasn't that I was a good shot, it was that all of them were so bad. They literally couldn't hit the side of a barn with a handful of beans.
