Interesting point here:
1. The CCs do often apply the guidance in their own way, but they are also involved in the writing of the Guide at the HO level.
2. A 'level playing field' is less-important than fair administration case by case. The former is often seen as requiring even more law/guidelines - which is always going to be an opportunity for the Police and HO to make things the same across the country, but worse than they are now. What is needed is well-informed and assertive applicants, who know how to handle the relevant police departments.
3, The problem with changes in both the law and Guide is not that the people making them know nothing about firearms. I suspect that this is the same thinking that makes BASC (for example) feel flattered and important when asked to 'help the HO out', only to find when the warm glow has worn off that they've approved some completely disastrous undermining of 100years of established equitable practice which favoured both fairness, antidiscrimination, and the spirit of the Act.
The problem is emphatically not the the civil servants don't know anything about firearms. The problem is completely the opposite: they know exactly what they're doing, and why, and they know how and when to advance their agenda. We, and our organisations, need to recognise this and act accordingly; by which I mean largely as individual shooters keeping our MPs on side: not necessarily on the side of shooting, but on the side of the spirit of the Firearms Act and of the fundamental freedoms which it protects.
