Why am I hearing in my head "This is my rifle, this is my gun ..." as sung by Gunny Hartman / R Lee Ermey (Full Metal Jacket)? Yeah, I know that 'guns' to the ignorant means any/all firearms! Perhaps this is the SOURCE of this tragedy, fail in proper nomenclature leading to carelessness in DANGEROUS usage! THREE such on a tray for someone to select THE PROPER ONE?
This is why experienced people talk about how bad 'learning experiences' lead to funerals! OSHA inspectors at all movie film locations?
Because your experience easily sees Hannah's inexperience ...
