This is a "double-edged sword" that is hanging over us all as gun owners.
If we just walk away, then WE won't get shot, but somebody else very well might. And then that produces the kind of publicity that gets ranges closed down and gun "control" laws passed.
If we stay, then maybe WE will get shot.
What we need is range safety officers who will deal with improper gun handling. But, they can't be there or see everything. So, we also need to TELL THEM what is troubling us.
A public range without a safety officer is in serious jeapordy of having an accident.
