As it happens I have spent quite a bit of time on police ranges. As well a lot of time on civilian ranges. IN MY EXPERIENCE... the safety violations on either were very rare, and continue to be rare. I'm sure that there are some departments out there with some inherent issues... Just as there must be civilian ranges with similar issues.
The Police absoloutly recieve more, and better training than the average shooter....
I agree, especially when police training satisfies POST standards.
And around here, most private citizens I see at public ranges have received virtually no proper training -- and that is reflected in their atrocious gun handling and abysmal marksmanship.
