I appreciate that they were non-confrontational.
But I'll ask the question again: if the gun is pointed safely down range, what in hell difference does it make?
Is this somehow more dangerous than actually firing the gun down range at a target?!
(That's the way I and my shooting buddies do it: gun pointed toward a target downrange, or toward the ground 15-20 feet in front of the line, thumb on hammer, pull trigger very gently until hammer is released, drop hammer slowly. It'll catch on the half-cock position if you're not careful; if so, repeat prior steps. Or, start from half-cocked. Something I do in life, if not on the range.)
