Don't seem like they give a s**t
And how the hell did the MoD get it's fingers up this data base?
A 5YO could see this is nothing but a blatant fishing expedition on a database they have virtually zero reason to access.
Got an intruder on a base. Take his dabs and pass to the PNC.
Worried about bogus employees. As above.
BTW for non UK readers MI5 and MI6 have nothing to do with the MoD and (AFAIK) haven't done so since WWI.
