Craig Murry, ex-ambassador and now full time thorn in the side of the government, had wanted to publish a book about the mercenary Tim Spicer. (As in he arranges soldiers to fight for other people; I've no idea what his attitude to money is).
But then the lawyers Schillings got involved and you can imagine the rest: legal threats, big court costs etc.
Upshot is that Craig's freedom of speech has been curtailed. Sure, he might have made mistakes in his book but we're not going to know and they've not been tested.
If you do want the ability to make your own mind up there's more here.
