Apologies if anyone has posted this before, but it's another drop in the bucket.
Remember Katharine Gun, the British government worker who revealed the Anglo-American efforts to spy on the UN? She was charged under the Official Secrets Act, and no matter what you think of her actions morally, she ought legally to have been dead meat. Well, she had her day in court today and the prosecution PRESENTED NO EVIDENCE, causing the case to be dropped. In a rather delicious touch, the prosecutor told the court that there was no "realistic prospect" of convicting her, despite her own admission that she had leaked the documents!
It turns out that her lawyer's threat to bring up the legality of the Iraq War -- and new evidence that that legality was challenged within the British government before the war began -- was enough to scare them off....
Further comment is really unnecessary. The full story is here.
