This is very true. I have read in multiple places over the years, that plice officers only have to qualify once per year if that. They don't even have to go to the range in most states, as long as they pass one little test they are good to go. It should be you need to pass multiple tests a year + have training with dummies and use blanks(more like training exercises they use in covert ops and higher level stuff).
I have gone out to target shoot and practice so much with my shotgun for example, that I almost never miss shooting a clay pidgeon . Ican throw them up in the air myself and shoot them, or throw 2 and get them both, i can have friends throw up them randomly and get them rapidly etc.
I am a really good shot with my ar-15, so much so that i can fire as fast as possible from 100 meters out and reliably land shots within a small grouping. Of course it took 100s of hours of learning how to shoot, how to lean in, hold gun, a few upgraddes to gun and sigh and all that, but i would be a way better person to have as a cop because Iam just so fluid with the gun and wouldn't immediately ever shoot someone. too much discipline.
I practice clearing my house with each weapon. where to stand, where a burglar would come in from, where they could stand.
I don't think cops do almost anything like this with their guns or training, and if they do I know at least in my state they only do it one time(before being hired), once hired zilch!
