I never imagined in my wildest dreams ever saying this, but I agree with Anotheoldgit when he writes, "All leaks should have a press veto on them, no good can come from allowing them to be aired."
As far as I am concerned, there is no such thing as a LEAKED document anyway, only a STOLEN one. In British politics, it seems to be acceptable that an e-mail between the Home Secretary and Prime Minister - seen by some disaffected minion and handed to the Shadow Home Secretary - should be blazoned around the British press. IS mail-theft acceptable?
On a personal level, if my accountant's secretary mistakenly puts a copy of a letter to another client in my envelope, is it OK for me to parade the financial knowlege this gives me around town to the detriment of the person concerned?
In cases where lives may be potentially put at risk - and I include open evidence to the London bombings inquest in the same category - there can be no justification whatsoever. (Yes, I appreciate that grieving relatives want answers and I have full sympathy for their loss, but their loved ones have already gone. No one else's life should be put at risk just to satisfy their need.)
