Srennaps, well done your daughter. I think most on here are not so much concerned with 'hang the guilty b^st^rd but how and why was all that information on the laptop in the first place.
Who actually supervised the procedures?
Now the men in grey suits are quite happy to say 'we make the policy and we can't be expected to resign if someone doesn't follow the rules.'
It is inconceivable that a junior officer could collect and collate all that material on his own. Someone, somewhere set up a system or process where he was able to get that data. Was it authorised by someone who has yet to hold his hand up?
Even the regional 1* is unlikely to have needed that quantity of data.
Just what was actually going on?
