The overly militarized police are more of a menace to society than some random gun owner.
This is SO asinine that words fail. The gun owner gave zero indication of any intent that would have drawn a "guns drawn jack-booted thug" raid. Old-fasioned polite service of a search warrant would almost certainly have been adequate.
He was a soft target. Too bad. Once those attempting confiscate guns start dying, they'll be less enthusiastic about the raids.
