Very interesting. Enough information to make it very worthwhile. Having some experience in the intelligence/security business I have always been surprised at the level of secrecy that continues to surround matters that have well passed their need to be classed secret or above. I appreciate that the UK secerity/secret services are governed by treaty obligations. I also appreciate that there are people that wish to expose matters of importance purely for the sake of doing so and that this has an adverse effect on disclosures by the intelligence services. This book has taken us a big step forward in understanding the valus of sigint.
