I'm working for a government department that issues guidance for the NHS to follow and I assume that the Home Office work in a similar way when they produce guidance for the police to follow. If that's the case, it won't be one person who's responsible for writing the guidance, it'll be dozens and dozens of experts having endless bloody meetings about every sentence and paragraph, then it'll be checked, double checked and triple checked by a team of editors trained to spot a misplaced comma at 30 paces.
The muppets are the people who amended the law in 1997 and put in two paragraphs that referred to each other.
Basically, the problem is Section 5 excludes 'air weapons' but the definition of an air weapon in the act says it's only an air weapon if it doesn't meet the criteria for section 5, leading you round and round in bloody circles.
They've effectively created a 'what came first, the chicken or the egg' question in the law
