Your last paragraph is the key one. I have already posted a link to the published consultation paper on fire arms and in there are references made to the way that the law is set up in Australia, Northern Ireland and a reference to Scotland as well. It is inevitable that Westminster will follow suit otherwise question and situations like the one that OP has brought up will have to be dealt with on daily basis. I wonder how much notice these organisation take of sensible objection put forward by relevant associations put forward on behalf of " affected " parties. The evidence so far points to nil.
