You may be completely correct of course in that take on it, more likely perhaps in regard to cop membership of pistol clubs/ranges.
My choice of action would be simply that other than A-cat occasional visitors on their initial 3 visits, ALL shooters at pistol range must be members. Best to state actions in positive rather than negative terms IMHO.
