NO! you clearly don't, MI5 is not a secret intelligence Service so to add it into the same category as CIA and MOSSAD, just makes me want to ignore your whole debate. Please don't talk to me till you get a better understanding of the subject!
I suggest reading Tinker, Tailor, Solider, Spy coupled with "The Farm".
Thanks!
It is difficult to protect people who do this kind of work, they are on "assignment" whilst at I so before then they were joe bloggs and after leaving they are joe bloggs again. Problem is, when you work in the gutter, you sometimes make friends that can be toxic to health!
Remember what happened to Gen Alvi, the man was the Grandfather of Zarar Coy.
