Personally I reckon there has been a bit of emailing been going on.
I know one of the strathclyde police dive team has a PPL and he ain't the shy retiring type. Especially in the Oban bar.
A couple of the Chief inspectors have been seen out in PIK in light aircraft so I wouldn't be suprised if the old emails have gone up then come down thanks to PPrune.
Maybe highlighting which forces have miss-information would clear things up.
