Like as has been said, officers who are serious shooters tend to be very good, and the ones who only shoot for mandatory qualification are not.
The good ones were probably good even before becoming police officers.
And which ones do you want to show up when you call 911?
Unfortunately there's no way to know.
If or when you see the cops rushing to the scene, it might be a good idea to vacate the place, like the folks in the video of this did.
