Mike it's a very simple answer. A few years back, myself and a few other fairly experienced (at least 4/5 years in PLD) members of staff left the department. We've not really been replaced in regards to numbers, but the inexperienced admin assistants (mainly good looking young girls straight from school) have been 'trained' up as replacements. They don't really have a knowledge outside of Lasors of what flight crew actually get up too. Any difficult question they get (and by that I mean something a tiny bit less then standard) they'll tend to fob off onto the policy department for them to answer, even though it's not a policy question as it's covered in lasors. The policy section are the ones that actually write and edit Lasors in order to avoid questions like this all together.
Crap reason, but none the less, it is the reason!
Not too worried about saying the above, not sure anyone there knows what pprune even is!
